We assessed all men diagnosed with a varicocele by two surgeons from 2017 to 2020, excluding those who did not undergo surgical treatment. Patients were stratified based on the presence of pain at clinical assessment, and these groups were compared. Logistic regression models were utilised to assess for predictors of pain. A total of 313 men were included, with relatively similar proportions completed by both surgeons (48.2% and 51.8%). A total of 98 (31.3%) had typical varicocele-associated pain at the time of assessment. The pain group was younger than the no pain group (30.5 versus. 35.0, respectively, p less then .01), and those with pain had greater varicocele grades (p = .008). Although not statistically different, there was a greater portion of left-sided only varicoceles in the pain group (p = .09). No significant differences were demonstrated between sperm concentration, motility, volume or morphology pre-operatively, or post-operatively between groups. Younger age and varicocele grade were predictive of varicocele-associated pain. In conclusion, almost 1/3 of men presented with varicocele-associated pain. Pain does not predict response to varicocelectomy, but these men tend to be younger, and have higher grade varicoceles.For metastasis formation, individual cells from a primary tumor must migrate toward other tissues. The aim of this study was to determine if mesenchymal stromal cells (MSCs) from human bone marrow are able to emit signals that induce this migratory activity in cancer cells. We separated the supernatant of MSCs derived from human bone marrow by size-exclusion and ion-exchange chromatography and have subsequently studied the migratory behavior of the prostate cancer cell line PC3 and the breast cancer cell line MDA-MB-231 toward the respective fractions in a transwell migration assay. We identified the extracellular matrix (ECM) proteins type I collagen, type III collagen, fibronectin, and laminin 421 as potential drivers of cancer cell migration. These results could be reproduced using the corresponding isolated or recombinant ECM proteins. SB203580 p38 MAPK inhibitor Knockdown of the gene encoding beta 1 integrin, an important cell surface receptor for fibronectin, has led to inhibition of cancer cell migration. This supports the hypothesis that beta 1 integrin signaling represents an initial event that leads to metastasis, and that signaling is triggered by binding of integrin heterodimers to ECM molecules. Further characterization of signaling factors and their respective receptors will have implications for anticancer drug development.

To describe the patterns of consumption of multiple sugary sweetened beverages (including modern and traditional) among adolescents in Ho Chi Minh City and to identify a possible relationship between this consumption and overweight and obesity and with other main factors.

A secondary analysis from a cross-sectional study of 11 to 15-year-old students from 31 junior high schools across Ho Chi Minh City. We measured the students' anthropometric status and assessed beverage consumption using a validated FFQ. Multivariate logistic regression models were used to identify the association between the consumption of sugar-sweetened beverages and obesity and other factors.

The sugar-sweetened beverages (SSB) ranged widely from modern soft drinks and powdered drinks to traditional sugar-added fruit, leaf juices and milk-based. These beverages were very popular among 2,660 participants with 36% consuming at least one variety daily. link2 Factors positively associated with the sugar-sweetened beverage consumption included a higher level of physical activeness, higher consumption of fast foods, and daily fruit and vegetable consumption. We found a negative association between milk-based SSBs with overweight & obesity status of the students, with every kcal more of fresh milk with sugar and condensed milk can reduce an odd of 0.005 (95%CI [0.002-0.008], p<0.001) and 0.004 (95%CI [0.002-0.010], p=0.044) consecutively. None of other SSBs was significantly related to adolescent overweight and obesity.

Milk based drinks potentially protect adolescents against overweight and obesity and further research to assess this protection is needed.

BACE1 enzyme is essential for the generation of Aβ. Deficiency of p38α-MAPK in neurons increases lysosomal degradation of BACE1 and decreases Aβ deposition in the brain of APP-transgenic mice. However, the mechanisms mediating effects of p38α-MAPK are largely unknown. In this study, we used APP-transgenic mice and cultured neurons and observed that deletion of p38α-MAPK specifically in neurons decreased phosphorylation of Snapin at serine, increased retrograde transportation of BACE1 in axons and reduced BACE1 at synaptic terminals, which suggests that p38α-MAPK deficiency promotes axonal transportation of BACE1 from its predominant locations, axonal terminals, to lysosomes in the cell body. In vitro kinase assay revealed that p38α-MAPK directly phosphorylates Snapin. By further performing mass spectrometry analysis and site-directed mutagenic experiments in SH-SY5Y cell lines, we identified serine residue 112 as a p38α-MAPK-phosphorylating site on Snapin. Replacement of serine 112 with alanine did abolish p38α-MAPK knockdown-induced reduction of BACE1 activity and protein level, and transportation to lysosomes in SH-SY5Y cells. Taken together, our study suggests that activation of p38α-MAPK phosphorylates Snapin and inhibits the retrograde transportation of BACE1 in axons, which might exaggerate amyloid pathology in AD brain.Shiftwork and circadian disruption are associated with adverse metabolic effects. Therefore, we examined whether clinical biomarkers of metabolic health are under endogenous circadian regulation using a 40 hours constant routine protocol (CR; constant environmental and behavioral conditions) and evaluated the impact of typical daily conditions with periodic sleep and meals (baseline; 8 hours sleep at night, four meals during a 16 hour wake episode) on the phase and amplitude of these rhythms. Additionally, we tested whether these circadian rhythms are reset during simulated shiftwork. Under CR (n = 16 males, mean age ± SD = 23.4 ± 2.3 years), we found endogenous circadian rhythms in cholesterol, HDL and LDL, albumin and total protein, and VLDL and triglyceride. The rhythms were masked under baseline conditions except for cholesterol, which had near-identical phases under both conditions. Resetting of the cholesterol rhythm and Dim Light Melatonin Onset (DLMO) was then tested in a study of simulated shiftwork ons for understanding how both behavioral changes and circadian shifts due to shiftwork may disrupt metabolic function.Foliar water uptake (FWU) occurs in plants of diverse ecosystems; however, the diversity of pathways and their associated FWU kinetics remain poorly resolved. We characterized a novel FWU pathway in two mangrove species of the Sonneratia genus, S. alba and S. caseolaris. Further, we assessed the influence of leaf wetting duration, wet-dry seasonality and leaf dehydration on leaf conductance to surface water (Ksurf ). The symplastic tracer dye, disodium fluorescein, revealed living cells subtending and encircling leaf epidermal structures known as cork warts as a pathway of FWU entry into the leaf. link3 Rehydration kinetics experiments revealed a novel mode of FWU, with slow and steady rates of water uptake persistent over a duration of 12 hr. Ksurf increased with longer durations of leaf wetting and was greater in leaves with more negative water potentials at the initiation of leaf wetting. Ksurf declined by 68% between wet and dry seasons. Our results suggest that FWU via cork warts in Sonneratia sp. may be rate limited and under active regulation. We conclude that FWU pathways in halophytes may require ion exclusion to avoid uptake of salt when inundated, paralleling the capacity of halophyte roots for ion selectivity during water acquisition.

There is a lack of understanding of the pathological and/or physiological nature of lumbosacral region pain.

To describe the gross variations of the osseous and soft tissues of the lumbosacral region and report the histological findings of sections of nerve tissue in affected and control horses.

Descriptive post-mortem case series.

All horses had undergone full clinical and gait assessment, including ridden exercise. Horses with a substantial response to infiltration of local anaesthetic solution around the sacroiliac joint regions were included in the affected group (n=27). Horses for which the source(s) of pain was confirmed by diagnostic anaesthesia to be distant to the lumbosacral region were included in the control group (n=5). The pelvic regions were isolated and the soft tissues were assessed grossly. Sections of the lumbosacral plexus and cranial gluteal, sciatic and obturator nerves were examined histologically. The osseous specimens were evaluated for anatomical variants and abnormalities. Dregion pain may reflect the presence of a number of pathological changes. Neural pain may play an important role in some horses.

Interferon-γ (IFNγ) is a central activator of immune responses in the liver and other organs. IFNγ triggers tissue injury and inflammation in immune diseases which occur predominantly in females for unknown reasons. Recent findings that autophagy regulates hepatotoxicity from proinflammatory cytokines led to an examination of whether defective hepatocyte autophagy underlies gender-specific liver injury and inflammation induced by IFNγ.

A lentiviral Atg5 knockdown to decrease autophagy sensitized AML12 hepatocytes to death from IFNγ in combination with IL-1β or TNF. Death was necrosis due to impaired energy homeostasis and ATP depletion. Male mice with decreased autophagy from a tamoxifen-inducible, hepatocyte-specific Atg5 knockout were resistant to IFNγ hepatotoxicity whereas female knockout mice developed liver injury and inflammation. Female mice had increased IFNγ-induced signal transducer and activator of transcription 1 (STAT1) levels compared to males. Blocking STAT1 but not interferon regulatory factor 1 signaling prevented IFNγ-induced hepatocyte death in autophagy-deficient AML12 cells and female mice. The mechanism of death is STAT1-induced overexpression of nitric oxide synthase 2 (NOS2) as in vitro hepatocyte death and in vivo liver injury were blocked by NOS2 inhibition.

Decreased hepatocyte autophagy sensitizes mice to IFNγ-induced liver injury and inflammation through overactivation of STAT1 signaling that causes NOS2 overexpression. Hepatotoxicity is restricted to female mice suggesting that gender-specific effects of defective autophagy may underlie the increased susceptibility of females to IFNγ-mediated immune diseases.
