Nowadays, Ephedra species have been marked as encouraging natural material for research in the field of pharmacology. This work provides an overview of the botanical, traditional uses, phytochemistry, pharmacological properties, molecular mechanisms, and toxicity of Ephedra alata. The following databases were utilized to search for primary literature references: PubMed, Web of Science, Scopus, Scientific Information Database, Science Direct, Google, and Google Scholar. The present review demonstrates that various compounds have been extracted from E. alata, such as fatty acids, sphingolipids, volatile compounds, reducing sugars, flavonoids, phenolic compounds, and alkaloids. These natural compounds show valuable biological activities, such as antioxidant, antimicrobial, anti-inflammatory, anticancer, antidiabetic, antihypertensive, anti-obesity, nephroprotective, hepatoprotective, antipyretic, analgesic, anti-acetylcholinesterase, antityrosinase, and anti-urease activities. Several mechanisms are proposed to understand the biological effects of E. alata. In summary, E. alata constitutes good natural material for utilization in food and medicine applications.

Mitochondria are the main cell organelles responsible for adenosine triphosphate production through cellular respiration. They also have roles in regulating other cellular processes, including reactive oxygen species, apoptosis, and others. The function and number of mitochondria are important for the maintenance of bone homeostasis. In recent years, the regulation of bone homeostasis by mitochondria has attracted particular interest. In addition, some natural compounds have been demonstrated to modulate mitochondria functions, such as resveratrol, quercetin, and curcumin, etc. Here, we review the recent discoveries concerning mitochondrial oxidative phosphorylation and bone formation, as well as the effects of some natural compounds (resveratrol, quercetin, and curcumin) on oxidative phosphorylation, and discuss their therapeutic implications in treating bone disorders.

Cytokine storm is a severe immune response that is characterized by the release of large amounts of inflammatory mediators (e.g., cytokines). 2′,5′-Dihydroxyacetophenone (DHAP) is a small molecule with a variety of biological activities involving antioxidant, anti-inflammation and antitumor. The primary objective of the current investigation is to elucidate the underlying mechanism of DHAP in cytokine storm and perform a preliminary analysis of its potential applications.

The roles of DHAP in cytokine storm were investigated in vitro and in vivo. The molecular basis of DHAP was also studied by network pharmacological analysis and molecular docking.

DHAP inhibited the production of inflammatory factors such as interleukin-1β, interleukin-6, and nitric oxide, alleviated the symptoms of the inflammatory response, and prolonged the survival of cytokine storm animal models. In vitro experiments showed that DHAP inhibited the proliferation of RAW264.7 cells in an inflammatory environment and suppressed the secretion of pro-inflammatory factors in RAW264.7 cells. Western blot results showed that DHAP increased the protein stability of Hdac1, decreased the acetylation level of P65, and inhibited the activation of the nuclear factor-kappa B signaling pathway.

DHAP protected against cytokine storm by repressing the excessive production of pro-inflammatory factors and attenuating immune responses. DHAP efficiently inactivated the nuclear factor-kappa B signaling pathway. Hdac1 may act as the potential target of DHAP to inhibit cytokine storm. DHAP is a potential treatment of cytokine storm and deserves further study.

Previous studies showed that tumors are associated with the increased inflammatory burden and neutrophil-to-lymphocyte ratio (NLR) is also associated with inflammatory conditions. However, there is no review on the role of NLR in meningioma. The goal of this study was to see if NLR has any prognostic and diagnostic value in meningioma.

The search was conducted on PubMed, Scopus, and Web of Science up to 3 August 2023. A total of 23 studies were included in the systematic review, of which 13 were included in the meta-analysis.

It was found that patients with high-grade meningioma had higher levels of NLR compared to those with low-grade meningioma (standardized mean difference [SMD] = 0.72, 95% confidence interval [CI]: 0.21–1.23, p = 0.006)]. In addition, we found that there was no difference between NLR levels of patients with meningioma and those with gliomas (SMD, −0.19, 95% CI: −0.47–0.10, p = 0.20). Also, higher levels of NLR were found in patients with meningioma compared with healthy controls (SMD = 0.56, 95% CI: 0.24–0.88, p = 0.01). Studies showed that an NLR > 2.4 differentiated high-grade and low-grade meningioma, an NLR > 2.74 differentiated high and low progression-free survival groups, and an NLR > 2.59 was associated with recurrence, with high sensitivity and specificity. However, the NLR did not predict postoperative pneumonia following meningioma resection. Because of the contradiction, our study did not clearly demonstrate the difference in NLR levels in meningioma and other pathologies, so more studies are needed on this subject.

NLR had significant diagnostic and prognostic value in meningioma. In general, we inferred a strong link between systemic inflammation assessed by NLR and meningioma, based on elevated levels of NLR in patients with meningioma compared to healthy controls. In addition, NLR had significant predictive potential for the progression and recurrence of meningioma. The predictive potential increased when combined with other diagnostic tools such as fibrinogen level. NLR may guide clinical decision making as an inflammatory marker and its relationship to therapeutic efficacy.

Our capacity to recognize and manage allosensitized transplant recipients and optimize organ allocation has been greatly improved by the development of single-antigen bead tests for detecting human leukocyte antigen antibodies. The main drawbacks of this technology have been thoroughly discussed in the literature, covering problems like artifacts that result in nonspecific background, variability, lack of uniformity, and difficulties in data interpretation. Consequently, it is not always easy to understand single-antigen bead data. This review will discuss the interpretation of donor-specific antibody data while considering the associated technical limitations. To ensure the correct clinical application of this test and to enhance the quality of antibody data used to support published clinical research in the era of epitope-based computational matching algorithms, a detailed understanding of the single-antigen bead assay is necessary.

Tuberculosis remains a global health concern, and its treatment usually involves potent first-line antitubercular drugs which are tempered by the risk of associated hepatotoxicity leading to noncompliance and drug resistance. In this review, medicinal plants with the potential of protection against antitubercular drug-induced hepatotoxicity in animal models were explored from scientific literatures.

From literature published between 1999 and 2022, this review systematically extracted 68 studies that reported on medicinal plants with protection against antitubercular drug-induced liver toxicity in animal models.

Isoniazid, pyrazinamide, rifampicin, and etambutol were the first-line drugs reported in the reviewed studies. The liver enzymes, antioxidant status, inflammatory markers, and improvement in the liver architecture were the criteria most frequently used by the reported studies to access hepatoprotection. These plants are rich in bioactive phytochemicals which exhibit their hepatoprotective properties via mechanisms such as antioxidant activity, anti-inflammatory effects, and detoxification enhancement.

This review provides the hepatoprotective properties and mode of action of medicinal plants and encourages future perspectives marked by rigorous scientific research, clinical trials, and integrative medicine approaches. Albeit the challenges of standardization of herbal formulation, safety concerns and hurdles of the regulatory framework must be addressed as traditional medicinal plants offer a promise to mitigate antitubercular drug hepatotoxicity.

The insulin/insulin-like growth factor (IGF) system has many receptors, signaling pathways, and ligands, making it highly complex. IGF1 increases the function of germ cells by increasing the synthesis of spermatogonia DNA and slowing down apoptotic cells. One of the most important objectives of this study was to investigate the function of fennel on the expression of the IGF1 gene in Kermani sheep testes.

The study involvedthree levels of fennel in the diets (20, 10, and zero g/kg dry matter), and tissue sampling was performed using testis tissue. Samples were rapidly placed in liquid nitrogen before being stored at -80°C. Then, total RNA was extracted and for the IGF1 gene (target) and GAPDH gene (reference), the real-time polymerase chain reaction was applied.

The outcomes displayed that increasing levels of fennel in the ration significantly (p < 0.05) increases the weight of the testis (0.35 kg and 0.36 kg at the levels of 1% and 2% fennel, respectively) compared to rations without fennel (0.29 kg at the levels of 0%). Association between testosterone and fennel feeding in studied lambs showed that adding fennel to the diet significantly (p < 0.05) increasesthe concentration of blood testosterone (3.5 ng/dL and 4.4 ng/dL at the levels of 1% and 2% fennel, respectively) compared with rations without fennel (1.7 ng/dL). The results showed that adding fennel to the diet significantly (p < 0.05) increases the amount of IGF1 gene expression in the testis (2.5 and 2.7 at the levels of 1% and 2% fennel, respectively) compared with rations without fennel (1 at the levels of 0% fennel).

Fennel has an affirmative effect on gene expression in the testis and can be added to sheep food rations to progress reproductive functions (by stimulating Leydig cell steroidogenesis, producing more sperm and testosterone, and growing and developing the testis).

Patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations benefit from targeted therapy with tyrosine kinase inhibitors (TKIs). Nevertheless, 50–70% of patients will experience progressive disease during TKI therapy, and nearly half will develop resistance mutations such as T790M, for which a third-generation TKI has been developed and proven to be highly effective. One of the most common sites of metastasis in patients with NSCLC is the central nervous system, significantly impacting their and their relatives’ quality of life as well as the management of the disease. A patient diagnosed with stage IV lung adenocarcinoma showed progression after 21 months of first-line anti-EGFR therapy and showed clear signs of neurological impairment. The interpretation of cerebral involvement was dubious and difficult: while cerebral spinal fluid cytology seemed to confirm leptomeningeal carcinomatosis, no meningeal nodules or abnormal enhancement was detected on magnetic resonance imaging. Liquid biopsy detected the resistance mutation T790M; hence, therapy was switched to the third-generation TKI osimertinib. The first instrumental re-evaluation revealed a partial response, with a reduction in both lung lesion dimensions and brain alterations. This case shows the effectiveness of osimertinib in treating patients with stage IV NSCLC with central nervous system and bone involvement.

Identifying potential high-risk groups of oxaliplatin-induced liver injury (OILI) is valuable, but tools are lacking. So artificial neural network (ANN) and logistic regression (LR) models will be developed to predict the risk of OILI.

The medical information of patients treated with oxaliplatin between May and November 2016 at 10 hospitals was collected prospectively. We used the updated Roussel Uclaf causality assessment method (RUCAM) to identify cases of OILI and summarized the patient and medication characteristics. Furthermore, the ANN and LR models for predicting the risk of OILI were developed and evaluated.

The incidence of OILI was 3.65%. The median RUCAM score with interquartile range was 6 (4, 9). The ANN model performed similarly to the LR model in sensitivity, specificity, and accuracy. In discrimination, the area under the curve of the ANN model was larger (0.920>0.833, p=0.019). In calibration, the ANN model was slightly improved. The important predictors of both models overlapped partially, including age, chemotherapy regimens and cycles, single and total dose of OXA, glucocorticoid drugs, and antihistamine drugs.

When the discriminative and calibration ability was given priority, the ANN model outperformed the LR model in predicting the risk of OILI. Other chemotherapy drugs in oxaliplatin-based chemotherapy regimens could have different degrees of impact on OILI. We suspected that OILI may be idiosyncratic, and chemotherapy dose factors may be weakly correlated. Decision making on prophylactic medications needs to be carefully considered, and the actual preventive effect needed to be supported by more evidence.

Polymorphisms of the interleukin (IL)-17 proinflammatory cytokine family (IL17A and IL17F) have been associated with kidney chronic allograft failure (CAF). To date, the impact of heritable differences in IL17F genes and CAF among kidney transplant patients from North America has not been reported. The objective of the study was to assess the association of five distinct polymorphisms in the IL17F gene with histopathological changes in chronic kidney allograft failure.

Two hundred eighteen kidney transplant recipients were enrolled. Surveillance biopsies were performed to evaluate 11 distinct histological markers and the combined grade of interstitial fibrosis and tubular atrophy, 6 to 12 months post-transplant. Using direct sequencing, the IL17F polymorphisms (-1507C/T rs1889570, -1165A/G rs1266828, -5046C/T rs7771511, -6328G/A rs766748, and -7488A/G rs763780) were genotyped in the 10 healthy volunteer samples followed by all kidney transplant recipients were genotyped for five IL17F gene polymorphisms using polymerase chain reaction and sequence-specific primers. The association was evaluated using both univariate and multivariate logistic regression analysis.

We observed weak associations of TC genotype of IL17F-1165 (rs1266828) and allele of IL17F -1507C (rs1889570) with glomerular sclerosis and interstitial fibrosis and tubular atrophy (p = 0.017 and p = 0.03) respectively. Allele C of IL-17 -1165C/T (rs1266828) was associated with better glomerular sclerosis (p = 0.004, odds ratio = 0.39) score.

Our findings demonstrate that IL17F SNPs were not associated with CAF and support our prior published results that production of pro-inflammatory cytokines is not a strong predictor of CAF.

Accumulating evidence highlights the association between the gut microbiota and liver cirrhosis. However, the role of the gut microbiota in liver cirrhosis remains unclear.

We first assessed the differences in the composition of the bacterial community between CCl4-induced liver cirrhosis and control mice using 16S rRNA sequencing. We then performed a two-sample Mendelian randomization (MR) analysis to reveal the underlying causal relationship between the gut microbiota and liver cirrhosis. Causal relationships were analyzed using primary inverse variance weighting (IVW) and other supplemental MR methods. Furthermore, fecal samples from liver cirrhosis patients and healthy controls were collected to validate the results of the MR analysis.

Analysis of 16S rRNA sequencing indicated significant differences in gut microbiota composition between the cirrhosis and control groups. IVW analyses suggested that Alphaproteobacteria, Bacillales, NB1n, Rhodospirillales, Dorea, Lachnospiraceae, and Rhodospirillaceae were positively correlated with the risk of liver cirrhosis, whereas Butyricicoccus, Hungatella, Marvinbryantia, and Lactobacillaceae displayed the opposite effects. However, the weighted median and MR-PRESSO estimates further showed that only Butyricicoccus and Marvinbryantia presented stable negative associations with liver cirrhosis. No significant heterogeneity or horizontal pleiotropy was observed in the sensitivity analysis. Furthermore, the result of 16S rRNA sequencing also showed that healthy controls had a higher relative abundance of Butyricicoccus and Marvinbryantia than liver cirrhosis patients.

Our study provides new causal evidence for the link between gut microbiota and liver cirrhosis, which may contribute to the discovery of novel strategies to prevent liver cirrhosis.

Visceral adipocytes, typically larger and more pro-inflammatory, are less sensitive to insulin action and more susceptible to apoptosis than subcutaneous adipocytes. Melatonin is an anti-inflammatory, anti-apoptotic, and temporal cue to several tissues, including adipose tissue. The modern lifestyle often involves irregular sleep-wake cycles, exposure to artificial light at night, and shift work, all of which suppress nocturnal melatonin secretion and could disrupt adipose tissue homeostasis. This study aimed to determine the effects of pinealectomy on the temporal expression of core clock components and apoptosis-related transcripts and proteins in rat retroperitoneal (RP) adipose tissue.

In silico analysis predicted putative binding sites of core clock components for Caspase genes. Eighty male Wistar rats were divided into either Sham-operated or Pinealectomized groups. Four weeks post-surgery, the animals were euthanized every 4 h over 24 h, and the RP tissue was processed for qRT-qPCR and ELISA.

The promoter and regulatory regions of caspases 3, 8, and 9 were predicted. The expression of apoptosis-related genes exhibited circadian rhythmicity in control animals. Pinealectomy resulted in a loss of Fas rhythmicity, altered the cosinor parameters of Bax, Bcl2, Casp3, and Casp9 expression, and increased the protein content of BAX, BCL2, CASP3, and CASP8 in the late dark phase. The daily expression of core clock components (Clock, Bmal1, Per2, Cry1, and Nr1d1) was significantly altered by the time main effect, while pinealectomy did not change their expression.

Melatonin plays important roles in the daily regulation of apoptosis in RP fat, suggesting that melatonin suppression due to a desynchronized modern lifestyle might contribute to the development of obesity and metabolic syndrome.

Inflammation is a natural reaction of the innate immune system that evolved primarily to protect the human body from invading pathogens and to heal injuries. There are two different types of inflammation, acute and chronic inflammation, differing in duration, underlying causes, and characteristics. The acute-to-chronic transition can be determined by several pathomechanisms, including dysregulation of immune response and failure to eliminate the underlying cause. Emerging evidence suggests that dysfunctional mitochondria can promote the development of chronic inflammation. In this respect, the mechanisms triggering defective mitophagy, a selective form of autophagy that exterminates dysfunctional mitochondria to maintain cellular homeostasis, attracted special attention. This review aims to summarize current evidence underlining the role and mechanisms of mitochondria in inflammation chronification, which will contribute to develop targeted therapeutic approaches to restore mitochondrial health and alleviate chronic inflammation that can be used for a wide range of chronic inflammatory diseases.

The coronavirus disease 2019 (COVID-19) pandemic continues to affect global health, and the emergence of new variants has added a layer of uncertainty to medical practice. Although elective surgeries are recommended to be postponed for at least 7 weeks after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to be considered safe, the safety and optimal timing for pancreatic surgery after this infection remains unknown.

Conducted in four high-volume pancreas centers in China, this prospective, multicenter clinical trial aimed to provide a realistic representation of the key perioperative parameters for pancreatic surgery after SARS-CoV-2 infection. The primary outcome was 30-day perioperative survival, and the secondary outcomes included major complications, pulmonary complications, and surgical complications.

Our results revealed that elective pancreatic surgery within 4 weeks of SARS-CoV-2 infection may be correlated with a prolonged hospital stay. Specifically, patients who underwent surgery within 0–2 weeks (24.7 days average) or 3–4 weeks (21.8 days average) after infection had obviously longer hospital stays compared to those without prior infection (15.5 days average) or those who underwent surgery more than 4 weeks after infection. However, there was no apparent increase in the total postoperative complications classified as Clavien-Dindo grade ≥ 3, even among patients who underwent surgery within 2 weeks after SARS-CoV-2 infection.

No significant increase in major complications is observed among patients undergoing pancreatic surgery following a diagnosis of SARS-CoV-2. However, it would be safer to perform pancreatic surgery at least 4 weeks after SARS-CoV-2 infection.

Gremlin-1 (GREM1) was recently reported to maintain the cellular heterogeneity of pancreatic cancer. However, the function of GREM1 in endometrial cancer remains elusive. The purpose of this study was to investigate the underlying mechanisms of GREM1 in endometrial cancer using an ensemble learning-based framework.

The training and test cohorts were gathered from The Cancer Genome Atlas and Genome Expression Omnibus databases, respectively. The cohorts were divided into low-GREM1 and high-GREM1 groups. Differentially expressed gene analysis, weighted gene co-expression network analysis, and Mfuzz clustering were implemented in the training cohort to screen genes with GREM1. The genes were subjected to machine learning-based integration for selecting key genes with GREM1. Together with the Bayesian network inference and Kyoto Encyclopedia of Genes and Genome enrichment analysis on key genes and GREM1, the potential pathway of GREM1 in endometrial cancer was illustrated. Leveraging the CIBERSORT analysis tool and single sample gene set enrichment analysis, the immune landscape of endometrial cancer was investigated to identify the immune cells with GREM1 and key genes.

A set of 10 key genes (FAP, THBS1, POSTN, INHBA, ASPN, COL3A1, IGFBP5, COL8A1, FN1, and COL5A2) highly linked to GREM1 were obtained. Moreover, GREM1 may regulate extracellular matrix-related pathways in endometrial cancer, affecting extracellular matrix degradation involving collagen-related key genes. Finally, we found increased infiltration of mast cells in the high-GREM1 group, accompanied by their positive correlations.

GREM1 regulated extracellular matrix modulation in endometrial cancer by interacting with key genes, with mast cells serving as a signature.

Human papillomavirus (HPV) has been clearly linked to the occurrence of some cancers such as cervical cancer, anogenital cancer, and head and neck cancer. However, studies suggest that the virus can also be the reason for other forms of malignant diseases. Traditionally, countries in the Middle East, including Iran, were thought to be less exposed to HPV infections due to conservative sexual customs. Moreover, owing to the lack of a proper vaccination program in adolescence, malignancies caused by the HPV virus are increasing and are of concern. Additionally, in the absence of a well-established vaccination schedule, changes in sexual behavior have resulted in an increasing number of young individuals engaging in premarital intercourse. In this article, we provide an overview of the current prevalence of common cancers in Iran closely associated with HPV, the status of vaccination programs aimed at preventing malignancies, and early detection strategies to halt cancer progression

The study aimed to analyze the prevalence, trends, and outcomes of twin pregnancies in Ile-Ife, Nigeria, over two distinct periods.

This research, based on a 14-year retrospective cohort study, scrutinized twin births occurring in two-time frames: recent years (2012–2018; Period II) and the recent past (2005–2011; Period I) at a University Teaching Hospital in Ile-Ife, Nigeria. The inclusion criteria were limited to twin births, excluding singleton and higher-order gestations. Outcomes were evaluated based on several parameters, including mode of delivery, birth weights, fetal gender combinations, APGAR scores, perinatal mortality, and maternal complications. Data analysis was conducted using the 26th version of Statistical Package for the Social Science, with a significance threshold of p < 0.05.

The study documented a stable prevalence of twin gestations, registering at 20.7 per 1,000 births without a significant discrepancy between the two time periods (21.7‰ versus 19.7‰; p = 0.699). Individuals from the Yoruba tribe predominantly featured in both cohorts, showing no considerable variation between the two time periods [83 (95.4) vs. 120 (99.2); p-value = 0.116]). The data exhibited recurrent instances of caesarean delivery (65.6% vs. 50.2%, p = 0.119), vertex-vertex presentation (38.0% vs. 44.7%, p = 0.352), and differing sex combinations (33.3% vs. 38.0%, p = 0.722) across both time frames. Twin II neonates born through Caesarean section were more frequently admitted to neonatal intensive care units than Twin I (5.1% versus 4.6%; p = 0.001). The recent years witnessed a surge in preterm labor complications, notably higher than the earlier period (17.1% versus 7.8%; p = 0.008).

The prevalence of twin births in Ile-Ife, Nigeria, demonstrates a fluctuating decline. To comprehensively understand the dynamics of twin births in the region, there is a pressing need for expansive, community-centric research in southwest Nigeria.

Recent technical advances in liver imaging and surveillance for patients at high risk for developing hepatocellular carcinoma (HCC) have led to an increase in the detection of borderline hepatic nodules in the gray area of multistep carcinogenesis, particularly in those that are hypointense at the hepatobiliary phase (HBP) and do not show arterial phase hyperenhancement. Given their potential to transform and advance into hypervascular HCC, these nodules have progressively attracted the interest of the scientific community. To date, however, no shared guidelines have been established for the decision management of these borderline hepatic nodules. It is therefore extremely important to identify features that indicate the malignant potential of these nodules and the likelihood of vascularization. In fact, a more complete knowledge of their history and evolution would allow outlining shared guidelines for their clinical-surgical management, to implement early treatment programs and decide between a preventive curative treatment or a watchful follow-up. This review aims to summarize the current knowledge on hepatic borderline nodules, particularly focusing on those imaging features which are hypothetically correlated with their malignant evolution, and to discuss current guidelines and ongoing management in clinical practice.

Nonalcoholic fatty liver disease (NAFLD) is commonly associated with obesity but can develop in normal-weight people (lean NAFLD). We compared outcomes in lean, overweight, and obese NAFLD.

This retrospective chart review included patients at Stanford University Medical Center with NAFLD confirmed by imaging between March 1995 and December 2021. Lean, overweight, and obese patients had body mass index of <25.0, >25.0 and <29.9, and ≥30.0 kg/m2 for non-Asian and >23.0 and ≥27.5 for overweight and obese Asian patients.

A total of 9061 lean (10.2%), overweight (31.7%), and obese (58.1%) patients were included. Lean patients were 5 years older than obese patients (53±17.4 vs. 48.7±15.1 years), more were female (59.6% vs. 55.2%), white (49.1% vs. 46.5%), had NASH (29.2% vs. 22.5%), cirrhosis (25.3% vs.19.2%), or nonliver cancer (25.3% vs. 18.3%). Fewer had diabetes (21.7% vs. 35.8%) or metabolic comorbidities (all p<0.0001). Lean NAFLD patients had liver-related mortality similar to other groups but higher overall (p=0.01) and nonliver-related (p=0.02) mortality. After multivariable model adjustment for covariates, differences between lean and obese NAFLD in liver-related, nonliver-related, and overall mortality (adjusted hazard ratios of 1.34, 1.00, and 1.32; p=0.66, 0.99, and 0.20, respectively) were not significant.

Lean NAFLD had fewer metabolic comorbidities but similar adverse or worse outcomes, suggesting that it is not benign. Healthcare providers should provide the same level of care and intervention as for overweight and obese NAFLD.
