Substances such as tobacco and cannabis can negatively modulate seminal parameters and sex hormones and lead to fertility problems in males. The present study aimed to determine the effect of cigarettes, dipping tobacco, and cannabis on semen parameters and sex hormones in infertile males. A total of 160 infertile healthy participants (cigarette smokers n = 40, dipping tobacco users n = 40, cannabis users n = 40 and infertile controls n = 40) were included in the study. Fasting blood samples were collected from all the participants using the aseptic technique, and semen samples were collected by masturbation following sexual abstinence of 2-7 days. The levels of serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were determined using ELISA. The serum level of FSH was significantly higher in cannabis users relative to the control group (p = 0.043). selleck chemicals A mild non-significant decrease in sperm count, serum LH and testosterone levels were observed in all drug users compared to controls. In conclusion, chronic use of tobacco and cannabis mildly modulates semen and hormonal parameters in infertile males.Considerable advancements have recently been achieved in porcine somatic cell nuclear transfer (SCNT), but the efficiency remains low. Donor cell size might play an important role in SCNT, but its effects in pigs remain unclear. This study aimed to evaluate the efficiency of porcine SCNT by selecting donor cells of suitable size. Porcine fetal fibroblasts (PFFs) were divided into three groups, group S (small, d ≤ 13 μm), group M (medium, 13 μm 18 μm), and their biological characteristics were analyzed. Next, SCNT was performed using PFFs of different sizes to evaluate the developmental potential of reconstructed embryos. The data showed that PFFs in groups S, M and L accounted for 17.5%, 47.7% and 34.8% of cells, respectively. Morphologically, cells in group S exhibited clear and regular cell membranes and nuclei, whereas cells in groups M and L displayed varying degrees of cell membrane protuberance, karyo-pyknosis, autophagy and mitochondrial abnormalities. In addition, the growth status and proliferation capabilities of cells in group S were significantly better than those of group M and group L. The percentage of cells at G0/G1 in group S and M were significantly greater than group L. The senescence rate of group S was lower than group M and group L. The apoptosis rate of group S was significantly lower than that of group L but comparable to that of group M . The cleavage rate of group S was also significantly greater than that of group M but comparable to that of group L . The blastocyst rate of group S was significantly greater than that of group M and group L. The blastocyst cell numbers of group S were also significantly greater than those of group M and group L. These findings suggested that small PFFs with a diameter of less than 13 μm are more suitable donor cells for SCNT in pigs.
For decades many patients with small cell lung cancer (SCLC) have been offered prophylactic cranial irradiation (PCI) to prevent brain metastases (BM). However, the role of PCI is debated in the modern era of increased brain magnetic resonance imaging (MRI) availability. BM in SCLC patients may respond to chemotherapy, and if a negative MRI is used in the decision to use of PCI in the treatment strategy, the timing of brain MRI may be crucial when evaluating the effect of PCI. This retrospective study investigates the impact of PCI outcomes in patients with SCLC staged with brain MRI prior to chemotherapy.

This study included 245 patients diagnosed SCLC/mixed NSCLC-SCLC treated between 2012 and 2019. The population was analyzed separately for limited disease (LS-SCLC) and extensive disease (ES-SCLC). Patients were divided into groups based on baseline brain MRI prior to chemotherapy and PCI. The primary endpoint was time to symptomatic BM. Secondary endpoints were overall survival (OS), and progression-frmatic BM and improved survival outcomes suggesting PCI as standard of care. Similar benefit of PCI in patients with ES-SCLC was not found.
Effect of long non-coding RNAs (lncRNAs) on intracranial aneurysm (IA) development has been identified, while the role of noncoding RNA activated by DNA damage (NORAD) in IA remains unexplored. We aimed to verify the impact of NORAD on IA through sponging microRNA-136-5p (miR-136-5p).

Ruptured and unruptured IAs were harvested from IA patients, and expression of NORAD, miR-136-5p, and KDM1A was determined. The vascular smooth muscle cells (VSMCs) were cultured and, respectively, transfected with altered NORAD, miR-136-5p, or lysine-specific demethylase 1 (KDM1A) to observe their effect on biological functions, as well as on contraction and synthesis-specific indices of VSMCs. Interactions between NORAD and miR-136-5p, and between miR-136-5p and KDM1A were confirmed.

NORAD and KDM1A were upregulated while miR-136-5p was downregulated in IA, especially in ruptured IA. NORAD overexpression or miR-136-5p inhibition accelerated proliferation and migration, and decelerated phenotypic switching and apoptosis of VSMCs. The effects of overexpressed NORAD on VSMCs were reserved by miR-136-5p upregulation or KDM1A knockdown. NORAD functioned as a competing endogenous RNA of miR-136-5p and miR-136-5p targeted KDM1A.

NORAD suppressed miR-136-5p, thus upregulating KDM1A to participate in IA formation and rupture by inducing phenotypic regulation of VSMCs.

The selected derivatives such as 9-4-tBu-Ph-Diyne (20p), 9-3,4-Di-Cl-Diyne (20k) and 9-3,4-Di-F-Diyne (22s) noscapinoids revealed improved predicted binding energy of -6.676 kcal/mol for 20p, -7.294 kcal/mol for 20k and -7.750 kcal/mol for 20s respectively in comparison to noscapine (-5.246 kcal/mol). These 1,3-diynyl derivatives (20p, 29k and 20s) were strategically synthesized in high yields by regioselective modification of noscapine scaffold and HPLC purified (purity is >96%). The decrease in intrinsic fluorescence of purified tubulin to 8.39%, 17.39% and 25.47% by 20p, 20k and 20s respectively, compared to control suggests their binding capability to tubulin. Their cytotoxicity activity was validated based on cellular studies using two human breast adenocarcinoma (MCF-7 and MDA-MB-231), a panel of primary breast tumor cells and one normal human embryonic kidney cell (293 T). The 1,3-diynyl noscapinoids, 20p, 20k and 20s inhibited cellular proliferation in all the cancer cells that ranged between 6.2 and 38.9 µM, without affecting the normal healthy cells (cytotoxicity is less then 5% at 100 µM). Further, these novel derivatives arrest cell cycle in the G2/M-phase, followed by induction of apoptosis to cancer cells. Thus, we conclude that 1,3-diynyl-noscapinoids have great potential to be a novel therapeutic agent for breast cancers.Communicated by Ramaswamy H. Sarma.In recent years, increasing attention to the utilisation of Front-Of-Pack Labels (FOPLs) as a tool to prompt individuals towards healthier food choices has been observed both in regulatory bodies and academic research. However, few theoretical models have been used to understand their role in consumer decision-making, as well as the antecedents that induce individuals to accept the information provided by the label, and to benchmark FOPL performance in different markets.Through a sequence of two studies conducted in Italy, France and the UK on 2812 primary grocery shoppers, we developed a new theoretical framework, the Front-Of-Pack Acceptance Model, applicable both in contexts in which FOPL are present, and in which they should be introduced. Our findings suggest a structural link between the usefulness and ease of use of the labels and the way consumers form their attitudes and intentions towards buying healthier products.
We aimed to investigate the factors affecting the development of atherosclerosis and the role of calcification inhibitors fetuin-A, matrix-Gla protein (MGP), osteoprotegerin (OPG) in atherosclerosis progress.

The study was planned to investigate the relationship of serum OPG, MGP and fetuin-A levels with the development of atherosclerosis in the stage 2-3-4-5 chronic kidney disease (CKD) patients who did not require dialysis treatment.

32 (17 female, 15 male) healthy individuals and 92 (49 females, 43 males) CKD patients were included. The mean carotid intima-media thickness (CIMT), C-reactive protein (CRP), fetuin-A, OPG and MGP of the two groups were compared statistically. In CKD patients, age, body mass index (BMI), CRP, triglyceride, urea, systolic blood pressure (SBP), fasting blood sugar have a positive linear relationship, fetuin-A, OPG, GFR have a negative linear relationship with CIMT. The mean CIMT, right CIMT, left CIMT, blood urea, CRP, urinary albumin excretion creatinine and age show a negative linear relationship with fetuin-A.

Fetuin-A levels begin to decline from the early stages of CKD and are significantly lower in patients with atherosclerosis as expressed with CIMT. This suggests that fetuin-A may be used as an early marker in CKD for increased cardiovascular risk. Early recognition of these risk factors is important and large-scale studies on vascular calcification inhibitors are needed.

Based on responses from about 3000 firefighters across the United States and Canada, it provides invaluable information about how firefighters associate environmental conditions, work tasks and other factors with heat strain. One-half of firefighters surveyed have experienced heat stress during their service. They can wear fully deployed turnout gear for two or more hours on fire scene, reinforcing the importance of turnout suit breathability as a factor in heat strain. Survey results are useful in weighing the comparative value of the total heat loss (THL) and evaporative heat resistance (Ref) for predicting turnout related heat strain. The survey findings support the inclusion of a performance criterion in the NFPA 1971 Standard for Firefighter Personal Protective Equipment based on limiting the Ref of turnout materials along with current THL requirement.
COVID-19 has been responsible for countless deaths during this time.

The main objective of this study was to determine if the referred fever of elderly patients admitted for COVID-19 was related to their mortality.

Data were obtained from the 2020 hospital admissions records of the Hospital de San Juan de Alicante, Spain.

Those patients without fever had a greater age and comorbidity. There was not a significant difference related to fever in in-hospital mortality.

Previous studies seem to indicate that fever in its early stages has a protective effect rather than a harmful one. Our results confirm this trend. No data have been found in the literature that express the differences of elderly patients admitted for COVID-19 who presented fever versus those who did not in the context of hospital admission.

No significant differences were detected in terms of mortality with respect to the fever variable. However, patients without fever present significantly different laboratory values that could indicate a greater severity in their evolutionary course.
