Defect-assisted surface modification of a g-CN@WC heterostructure for tetracycline degradation: DFT calculations, degradation pathways, and nematode-based ecological assessment.

Eliminating hazardous antibiotics from aquatic environments has become a major concern in recent years. Tetracycline (TC) compounds pose a challenge for the selective degradation of harmful chemical groups.

Reliability of high-quantity human brain organoids for modeling microcephaly, glioma invasion and drug screening.

Brain organoids offer unprecedented insights into brain development and disease modeling and hold promise for drug screening. Significant hindrances, however, are morphological and cellular heterogeneity, inter-organoid size differences, cellular stress, and poor reproducibility. Here, we describe a method that reproducibly generates thousands of organoids across multiple hiPSC lines.

Tuning of Oxygen Vacancies in CoO Electrocatalyst for Effectiveness in Urea Oxidation and Water Splitting.

The development of an excellent multifunctional electrocatalyst that is based on non-precious metal is critical for improving the electrochemical processes of the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER), and the urea oxidation reaction (UOR) in alkaline media. This study demonstrates that incorporating Mo into CoO facilitated the formation of rich oxygen vacancies (Vo), which promotes effective nitrate adsorption and activation in urea electrolysis. Subsequently, in situ/operando X-ray absorption spectroscopy is used to explore the active sites in Mo-CoO-3 under OER, indicating the oxygen vacancies are first filled with OH in Mo-CoO; facilitated the pre-oxidation of low-valence Co, and promoted the reconstruction/deprotonation of intermediate Co-OOH.

Protonated CN Nanosheets for Enhanced Energy Storage in Symmetric Supercapacitors through Hydrochloric Acid Treatment.

Next-generation electrochemical energy storage materials are essential in delivering high power for long periods of time. Double-layer carbonaceous materials provide high power density with low energy density due to surface-controlled adsorption. This limitation can be overcome by developing a low-cost, more abundant material that delivers high energy and power density.

Inhibiting centrosome clustering reduces cystogenesis and improves kidney function in autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is a monogenic disorder accounting for approximately 5% of patients with renal failure, yet therapeutics for the treatment of ADPKD remain limited. ADPKD tissues display abnormalities in the biogenesis of the centrosome, a defect that can cause genome instability, aberrant ciliary signaling, and secretion of pro-inflammatory factors. Cystic cells form excess centrosomes via a process termed centrosome amplification (CA), which causes abnormal multipolar spindle configurations, mitotic catastrophe, and reduced cell viability.

Improved supercapacitor application of manganese ferrite nanoparticles via co-precipitation technique.

The novel co-precipitation technique has been employed to create the manganese ferrite nanoparticle. The prepared sample was annealed for various temperatures 400 °C, 600 °C and 700 °C. Based on TG/DT analysis the optimal temperature was found to be 700 °C and further additional analysis was performed for the sample annealed at 700 °C.

Generation of iPSC-derived human forebrain organoids assembling bilateral eye primordia.

Induced pluripotent stem cell-derived brain organoids enable the developmental complexities of the human brain to be deconstructed. During embryogenesis, optic vesicles (OVs), the eye primordium attached to the forebrain, develop from diencephalon. However, most 3D culturing methods generate either brain or retinal organoids individually.

Emergence of Mycobacterium orygis-Associated Tuberculosis in Wild Ruminants, India.

Tuberculosis caused by Mycobacterium orygis was detected in 2 spotted deer from a wildlife sanctuary in western India and an Indian bison from a national park in central India. Nationwide surveillance is urgently required to clarify the epidemiology of the Mycobacterium tuberculosis complex at the human-livestock-wildlife interface.

Clinicopathological investigation of nutritional osteodystrophia fibrosa in a flock of young stall-fed goats.

Background: Osteodystrophia fibrosa (ODF) is a metabolic disorder affecting the skeletal system, causing progressive loss of calcified bone mass and its replacement with fibrous tissue, which may be a sequel to primary or secondary hyperparathyroidism. This report intends to document the clinicopathological findings of ODF in a flock of young goats fed primarily on a wheat bran-rich diet.

Case Description: In a flock of 50 stall-fed goats aged 1 to 2 years, seven were clinically presented with bilateral facial enlargement, leading to dyspnea and difficulty in prehension and mastication.

Molecular epidemiological studies on avian pathogenic Escherichia coli associated with septicemia in chickens in India.

Bacterial septicemia causes huge economic losses in the poultry industry and there is no systematic research available in India on the connection of various pathogens associated with septicemia. The present molecular epidemiological study was conducted to investigate the association of different bacterial and immunosuppressive viral pathogens in septicemia suspected chickens. A total of 443 chicken carcasses with septicemic conditions from 71 different flocks were included in this study.

Newcastle Disease Virus Vectored Chicken Infectious Anaemia Vaccine Induces Robust Immune Response in Chickens.

Newcastle disease virus (NDV) strain R2B, with an altered fusion protein cleavage site, was used as a viral vector to deliver the immunogenic genes VP2 and VP1 of chicken infectious anaemia virus (CIAV) to generate a bivalent vaccine candidate against these diseases in chickens. The immunogenic genes of CIAV were expressed as a single transcriptional unit from the NDV backbone and the two CIA viral proteins were obtained as separate entities using a self-cleaving foot-and-mouth disease virus 2A protease sequence between them. The recombinant virus (rR2B-FPCS-CAV) had similar growth kinetics as that of the parent recombinant virus (rR2B-FPCS) in vitro with similar pathogenicity characteristics.

Glioblastoma multiforme (GBM) possesses glioma stem cells (GSCs) that promote self-renewal, tumor propagation, and relapse. Understanding the mechanisms of GSCs self-renewal can offer targeted therapeutic interventions. However, insufficient knowledge of GSCs' fundamental biology is a significant bottleneck hindering these efforts.

Human brain organoids assemble functionally integrated bilateral optic vesicles.

During embryogenesis, optic vesicles develop from the diencephalon via a multistep process of organogenesis. Using induced pluripotent stem cell (iPSC)-derived human brain organoids, we attempted to simplify the complexities and demonstrate formation of forebrain-associated bilateral optic vesicles, cellular diversity, and functionality. Around day 30, brain organoids attempt to assemble optic vesicles, which develop progressively as visible structures within 60 days.
