The results showed that FGL1 was downregulated significantly in most of the HCC cells lines and HCC tissues, corresponding to the results of the bioinformatics and western blot analyses. FGL1 expression level in HCC was found to be correlated to Edmondson grade and metastasis of the HCC. Additionally, high FGL1 expression was associated with better overall survival in HCC patients, suggesting that FGL1 could function as a tumor suppressor.

The expression level of FGL1 can be correlated with the progression and prognosis of HCC, suggesting its potential as a prognostic biomarker.

This Enteric methane is the largest component of total carbon footprints produced by livestock production system and its reduction is today's new challenge to make livestock farming sustainable for earth's environment. The production of enteric methane in ruminants is a complex phenomena involving different host factors like host genotype, rumen microbiome, host physiology along with dietary factors. Efforts have been made to reduce methane emissions largely through nutritional interventions and dietary supplements, but permanent reductions can be obtained through genetic means by selecting and breeding of low methane emitting animals. From genome-wide association studies, many important genomic QTL regions and single nucleotide polymorphisms involved in shaping the composition of the ruminal microbiome and thus their carbon footprints have been recognised, implying that methane emission traits are quantitative traits. The major bottleneck in implementation of reduced methane emission traits in the breeding programs is wide variation at phenotypic level, lack of precise methane measurements at individual level. Overall, the heritability for CH4 production traits is moderate, and it can be used in breeding programmes to target changes in microbial composition to reduce CH4 emission in the dairy industry for far-reaching environmental benefits at the cost of a minor reduction in genetic gain in production traits.

Conjunctivitis is one of the most common ocular pathologies. Its treatment depends on its etiology, but an excessive use of antibiotics and corticosteroids, which in many cases are contraindicated, has been described. The objective was to describe the prescription patterns of medications used to treat conjunctivitis in a Colombian population.

This was a cross-sectional study on the pharmacological treatment of patients diagnosed with conjunctivitis between April 1, 2020, and March 31, 2021; based on a drug-dispensing database of approximately 8.5million people affiliated with the Colombian Health System. Some sociodemographic and pharmacological variables and comorbidities were considered. A descriptive analysis was performed.

A total of 8708 patients were identified; they had a median age of 44.7years, and 59.3% were women. The most common causes of conjunctivitis were unspecified (53.1%) and allergic (37.4%). The most commonly used drug was olopatadine (26.1%), followed by dexamethasone with neomycin and polymyxin B (25.0%). A total of 97.0% of the patients received ophthalmic prescriptions, while 12.8% received systemic medications. Glucocorticoids (40.3%), antibiotics (37.7%) and antihistamines (31.7%) were the most commonly used groups of ophthalmic drugs. Glucocorticoids and ophthalmic antibiotics were the medications most frequently prescribed by general practitioners for the treatment of viral or bacterial conjunctivitis.

Many patients with conjunctivitis are not being managed according to the recommendations of clinical practice guidelines, which highlights that the widespread use of antibiotics with ophthalmic glucocorticoids could be considered potentially inappropriate prescriptions in many cases.

To determine the two-year results of small incision lenticule extraction (SMILE) for correcting post-keratoplasty myopia and myopic astigmatism.

In this case-series study, 10 eyes of 10 patients with a 6- to 10-year history of successful deep lamellar keratoplasty (DALK) underwent SMILE using the VisuMax laser platform. Ophthalmologic examinations and visual acuity and refraction measurement were taken pre- and 1, 3, 6, 12, and 24months postoperatively. The Pentacam and Sirius imaging were done in the first and last follow-up sessions.

The mean age of the patients was 39.60 ± 7.86years. Six subjects were male. Two years after SMILE, the mean improvement in UDVA and CDVA was 3.60 ± 1.84 (P < 0.001) and 1.60 ± 2.91 (P = 0.231) LogMAR, respectively. The mean decrease in spherical equivalent, spherical error, and cylinder power was 1.92 ± 1.96 diopter (D) (P = 0.013), 0.70 ± 3.05D (P = 0.213), and 2.42 ± 2.91D (P = 0.024), respectively. The vector mean target-induced astigmatism, surgical-induced astigmatism, and difference vector were 1.30D@44˚, 1.11D@24˚, and 0.86D@73˚, respectively. Two years after SMILE, vertical coma, horizontal coma, and spherical aberration increased by 0.44 ± 0.51, 0.23 ± 0.32, and 0.02 ± 0.16µm, respectively, (all P > 0.05) while trefoil reduced by 0.29 ± 0.75µm (P = 0.428).

SMILE can be an effective procedure for reducing refraction and astigmatism after DALK in patients with moderate myopia and moderate to severe astigmatism and improves the visual acuity in these patients. Axis rotation during surgery may result in under-correction of astigmatism. see more Refinement of SMILE treatment nomogram for post-DALK cases seems necessary.

Henle's fiber layer (HFL) is hyporeflective and indistinct on pupil-centered optical coherence tomography (OCT). However, a small area of HFL is also found to be hyperreflective on pupil-centered OCT. This study characterized the hyperreflective HFL of healthy eyes on pupil-centered OCT and investigated the possible physiological and functional relationship of hyperreflective HFL.

Subjects with different degrees of ametropia underwent a complete ophthalmologic examination, including binocular function by synoptophore and Titmus test, ocular axial length, refractions, and pupil-centered OCT angiography coupled with OCT. The area of hyperreflective HFL was manually plotted and calculated using the Optovue AngioVue system technology. The possible ocular physiological and functional relationship with the area of hyperreflective HFL was investigated.

A total of 111 subjects (222 eyes) without other ocular diseases were enrolled, of which 164 eyes (74%) presented hyperreflective HFL. The average area of hyperreflective HFL was 0.71 ± 0.07mm

. The area of hyperreflective HFL was significantly related to spherical diopters (P = 0.032). The average binocular area of hyperreflective HFL was 1.38 ± 0.17mm

. The binocular area of hyperreflective HFL was significantly related to the angle of superposition and far stereoacuity (P = 0.013 and 0.038, respectively).

Most healthy eyes present a small area of hyperreflective HFL, which might be due to alternation of the orientation of some Henle fibers by ametropia during the development of visual function postpartum. The small area of hyperreflective HFL may serve as a marker in identifying the boundary of HFL on OCT.

The effective mission of glia depends on their activation, release of cytokines, and oxidative cleaning of debris material from neuronal cells. Accumulating evidence indicates that microglia activation-induced oxidative stress via the activation Ca2+ permeable TRPV1 channel has an essential role in the pathophysiology of neurodegenerative diseases. However, there is scarce information on the cytosolic localization of TRPV1 and the induction of oxidative cytotoxicity in the glia. Hence, we investigated the interactions between cytosolic TRPV1 expression levels and oxidative neurotoxicity in the BV2, C8-D1A, N9 glia, and DBTRG glioblastoma cells. We observed TRPV1 expression in the perinuclear area but not in the cell membrane in the BV2, C8-D1A, and N9 cells. Hence, we observed no activation of TRPV1 on the increase of mitochondrial free reactive oxygen species (mROS) and apoptosis in the cells after the capsaicin stimulation. However, we observed TRPV1 channel expression in the positive control (DBTRG) cell membranes. Hence, the Ca2+ influx, TRPV1 current density, apoptosis, and mROS levels were increased in the DBTRG cells after the capsaicin stimulation, although their levels were diminished by the treatment of the TRPV1 blocker (capsazepine). In conclusion, the presence of TRPV1 in the cell membrane of DBTRG cells induced excessive generation of mROS and apoptosis actions, although the presence of TRPV1 in the perinuclear area did not cause the actions. It seems that there is a subtype of TRPV1 in the perinuclear area, and it is not activated by the capsaicin.Savar Upazila in the Dhaka District is a rapidly expanding city with a diverse range of industries and agricultural activities. This expansion poses environmental challenges including the threat to groundwater contamination. Based on these considerations, the objective of this research is to carry out a shallow groundwater hydrogeochemical characterization and an assessment of the suitablity of the groundwater for drinking and irrigational purposes using a geochemical approach, multivariate statistical techniques, and some indices of groundwater quality. The hydrogeochemical analyses of 42 groundwater samples from shallow depths (18 - 76 m) showed that the order of concentrations of cations, anions, and metals was Ca2+ > Na+ > Mg2+ > K+, HCO3- > Cl- > SO42- > NO3-, and Cr > As > Pb > Mn > Fe, respectively. Weathering of silicates was found to be the most significant hydrogeochemical process governing the chemistry of groundwater. Cation exchange also plays a significant role in the evolution of the groundwater chemistry. Principal component analysis and hierarchical cluster analysis suggested that anthropogenic activities are influencing groundwater quality. A drinking water quality index map showed that about 91% of the groundwater samples were in the excellent category and suitable for human consumption, with only a few samples exceeding the standards of the WHO and Bangladesh for concentrations of Ca2+, Mg2+, HCO3-, Fe, Mn, and As. An analysis of irrigation quality parameters found that most of the groundwater samples were either excellent or good for agricultural uses, except for one sample in the Tetuljhora Union that was unsuitable based on residual sodium carbonate. This finding may be useful to local governments in understanding the current status of groundwater quality, tracking potential threats of contamination, and initiating appropriate measures for long-term groundwater resource management.
