Association of serum steroids with survival in metastatic hormone-sensitive prostate cancer.

The CHAARTED study showed that adding docetaxel (Doc) to androgen deprivation therapy (ADT) in men initiating treatment for metastatic hormone-sensitive prostate cancer (mHSPC) prolongs survival, particularly in high-volume disease. Androgens drive both mHSPC and metastatic castration-resistant prostate cancer (mCRPC). Lower nadir serum testosterone concentrations are associated with better outcomes in men treated with ADT for biochemical relapse, while higher androgens at mCRPC are associated with better prognosis and increased benefit from abiraterone.

Effects of Mentha on blood pressure: a GRADE-assessed systematic review and meta-analysis of randomized controlled trials.

Background: Mentha consumption may associated with blood pressure improvement in humans, but the recent evidence from randomized controlled trials (RCTs) showed inconsistent results. The present study provides a systematic review and meta-analysis of RCTs to investigate the effect of Mentha on blood pressure.

Methods: To cover all relevant literature, a complete search was conducted across PubMed, ISI Web of Science, and SCOPUS databases before March 2024 using PRISMA guidelines.

HSD3B1, prostate cancer mortality and modifiable outcomes.

Androgen receptor stimulation by testosterone and dihydrotestosterone is crucial for prostate cancer progression. Despite the initial effectiveness of androgen deprivation therapy (ADT), castration-resistant prostate cancer eventually develops in most men. A common germline missense-encoding polymorphism in HSD3B1 increases extra-gonadal androgen biosynthesis from adrenal precursors owing to increased availability of the encoded enzyme 3β-hydroxysteroid dehydrogenase 1 (3βHSD1) - hence, it is called the adrenal-permissive enzyme.

Implications of glioblastoma-derived exosomes in modifying the immune system: state-of-the-art and challenges.

Glioblastoma is a brain cancer with a poor prognosis. Failure of classical chemotherapy and surgical treatments indicates that new therapeutic approaches are needed. Among cell-free options, exosomes are versatile extracellular vesicles (EVs) that carry important cargo across barriers such as the blood-brain barrier (BBB) to their target cells.

Targeting ZNF638 activates antiviral immune responses and potentiates immune checkpoint inhibition in glioblastoma.

Viral mimicry refers to the activation of innate anti-viral immune responses due to the induction of endogenous retroelement (RE) expression. Viral mimicry has been previously described to augment anti-tumor immune responses and sensitize solid tumors to immunotherapy including colorectal cancer, melanoma, and clear renal cell carcinoma. Here, we found that targeting a novel, master epigenetic regulator, Zinc Finger Protein 638 (ZNF638), induces viral mimicry in glioblastoma (GBM) preclinical models and potentiates immune checkpoint inhibition (ICI).

Relationship between emotional eating and nutritional intake in adult women with overweight and obesity: a cross-sectional study.

Background: Emotional eating (EE) is particularly prevalent in overweight or obese women, who may turn to food as a way to cope with stress, sadness, or anxiety. Limited research has been conducted on the association between EE and nutritional intake. Therefore, present study was designed to explore this association in adult women with overweight and obesity.

The reovirus variant RP116 is oncolytic in immunocompetent models and generates reduced neutralizing antibodies to Type 3 Dearing.

The mammalian reovirus Type 3 Dearing (T3D) is a naturally occurring oncolytic virus. We previously identified a T3D variant isolated from persistently infected cancer cells that has a premature stop codon mutation in the gene, generating a truncated σ1-attachment protein that lacks the globular head. We now report on the molecular characterization of this variant, named RP116, and assess its antitumor potential in human cancer cells and syngeneic mouse models.

Nectarine core-derived magnetite biochar for ultrasound-assisted preconcentration of polycyclic aromatic hydrocarbons (PAHs) in tomato paste: A cost-effective and sustainable approach.

A novel ultrasound-assisted magnetic solid-phase extraction coupled with gas chromatography-mass spectrometry (US-MSPE-GC/MS) was developed to detect trace amounts of polycyclic aromatic hydrocarbons (PAHs) in tomato paste, using a magnetic biochar adsorbent derived from nectarine cores. The highest extraction recovery was attained under 10 mg adsorbent mass, 30 min extraction time, 9 % (/) sodium chloride, and elution with 200 μL of dichloromethane. Under optimum conditions, the method demonstrated excellent linearity (R > 0.

Comparison of the effect of chewing gum with routine method on ileus after burns: a randomized clinical trial.

Background: Chewing gum is a healthy, cheap, and familiar solution for patients with premature irritation of the stomach and intestines. This study compared the effect of chewing gum and the routine method on ileus after burns.

Methods: This study is a randomized clinical trial conducted in Valiasr Hospital in Arak, Markazi Province, in the center of Iran, from December 2021 to February 2023.

Association between Dietary Intake, Profibrotic Markers, and Blood Pressure in Patients with Chronic Kidney Disease.

Background: Among profibrotic and oxidant factors, matrix metalloproteinases (MMPs) and advanced glycation end products (AGEs) have a major impact on the progression of chronic kidney disease (CKD). However, very limited studies evaluated the relationships between nutrient intake and the mentioned factors in patients with CKD. Therefore, the present study aimed to investigate the correlation between dietary intake and the levels of MMPs, AGEs, and blood pressure (BP) in these patients.

Breast cancer-related lymphedema: A critical review on recent progress.

Lymphedema is a chronic and debilitating condition characterized by an abnormal buildup of protein-rich fluid in the interstitial tissue, leading to the development of edema and tissue structural alterations. Breast cancer-related lymphedema (BCRL) remains a significant healthcare burden because it can develop within days and up to 11-years after the surgery. Specifically, axillary lymph node dissection leads to 30-50 % upper limb lymphedema, which involves the accumulation of protein-rich fluid.

Androgen production, uptake, and conversion (APUC) genes define prostate cancer patients with distinct clinical outcomes.

BACKGROUNDProstate cancer (PC) is driven by aberrant signaling of the androgen receptor (AR) or its ligands, and androgen deprivation therapies (ADTs) are a cornerstone of treatment. ADT responsiveness may be associated with germline changes in genes that regulate androgen production, uptake, and conversion (APUC).METHODSWe analyzed whole-exome sequencing (WES) and whole-transcriptome sequencing (WTS) data from prostate tissues (SU2C/PCF, TCGA, GETx).

HSD3B1 genotype and outcomes in metastatic hormone-sensitive prostate cancer with androgen deprivation therapy and enzalutamide: ARCHES.

HSD3B1 encodes 3β-hydroxysteroid dehydrogenase-1, which converts adrenal dehydroepiandrosterone to 5α-dihydrotestosterone and is inherited in adrenal-permissive (AP) or adrenal-restrictive forms. The AP allele is linked to castration resistance, mainly in low-volume tumors. Here, we investigate the association of HSD3B1 alleles with outcomes in ARCHES, a multinational, double-blind, randomized, placebo-controlled phase 3 trial that demonstrated clinical benefit with enzalutamide plus androgen deprivation therapy (ADT) in men with metastatic hormone-sensitive prostate cancer (mHSPC) compared to those treated with placebo plus ADT.

Comparison of Pb-based and Sn-based perovskite solar cells using SCAPS simulation: optimal efficiency of eco-friendly CsSnI devices.

In this study, we employed the one-dimensional solar cell capacitance simulator (SCAPS-1D) software to optimize the performance of Pb-based and Sn-based (Pb-free) all-inorganic perovskites (AIPs) and organic-inorganic perovskites (OIPs) in perovskite solar cell (PSC) structures. Due to the higher stability of AIPs, the performance of PSCs incorporating Cs-based perovskites was compared with that of FA-based perovskites, which are more stable than their MA-based counterparts. The impact of AIPs such as CsPbCl, CsPbBr, CsPbI, CsSnCl, CsSnBr, and CsSnI, as well as including FAPbCl, FAPbBr, FAPbI, FASnCl, FASnBr, and FASnI, was investigated.

The effects of probiotics supplements on metabolic indices and clinical signs in patients with diabetic retinopathy, a randomized double blind clinical trial.

Purpose: This study was carried out to evaluate the effects of probiotics administration on clinical status and metabolic profiles in diabetic retinopathy (DR) patients.

Methods: This randomized, double-blind, placebo-controlled trial was conducted among 72 DR patients. Subjects received probiotics including , , , daily (2 × 10 CFU/each strain) ( = 36) or placebo (starch) ( = 36) and were instructed to take one capsule daily for 12 weeks.

Elevated periprostatic androgens, sneaky testosterone and its implications.

A subset of men with prostate cancer have elevated periprostatic androgens compared with levels in peripheral blood (termed the sneaky T phenomenon), which are associated with poor clinical outcomes after radical prostatectomy. These androgens are of testicular origin and reach the prostate, presumably through venous shunting. Varicocele physiology is accompanied by increased hydrostatic pressure within the pelvic venous system, providing a theoretical mechanistic explanation for the sneaky T phenomenon.

Androgen loss weakens anti-tumor immunity and accelerates brain tumor growth.

Many cancers, including glioblastoma (GBM), have a male-biased sex difference in incidence and outcome. The underlying reasons for this sex bias are unclear but likely involve differences in tumor cell state and immune response. This effect is further amplified by sex hormones, including androgens, which have been shown to inhibit anti-tumor T cell immunity.
