N-functionalized calcium alginate encapsulated with microalgae for efficient Pb removal: Mechanisms and performance in batch and column operations.

In this study, a novel adsorbent called Ca@SP was developed by immobilizing microalgae protein (Spirulina platensis, SP) in an alginate matrix for enhanced Pb²⁺ removal from aqueous solutions. Synthesized via in situ crosslinking, Ca@SP leverages the synergistic effects of alginate's gel-forming ability and SP's N-rich biomass. Characterization of Ca@SP revealed a green spherical hydrogel with a BET specific surface area of 159.

IMU sensors attached to the lumbar region recorded acceleration and gyroscope data, which were then analyzed using DTW to quantify gait stability.

Effect of high-flow nasal cannula therapy on mechanical ventilation duration in the pediatric intensive care unit.

Background: High-flow nasal cannula (HFNC) therapy has gained popularity in the pediatric intensive care unit (PICU). However, the nationwide effect of HFNC on mechanical ventilation duration has not been studied.

TMEM135 deficiency improves hepatic steatosis by suppressing CD36 in a SIRT1-dependent manner.

Objectives: Dysregulation of lipid homeostasis pathway causes many liver diseases, including hepatic steatosis. One of the primary factors contributing to lipid accumulation is fatty acid uptake by the liver. Transmembrane protein 135 (TMEM135), which exists in mitochondria and peroxisomes, participates in intracellular lipid metabolism.

Immunohistochemical Expression and Significance of Preferentially Expressed Antigen in Melanoma (PRAME) in Gynecological Tumors: A Single-institution Retrospective Analysis.

Background/aim: Although preferentially expressed antigen in melanoma (PRAME) has been used as a diagnostic marker for malignant melanoma (MM), it is also expressed in various other malignancies. PRAME expression is rarely reported in female genital tumors. This study aimed to evaluate PRAME expression and its significance in gynecological malignancies.

Recent Advances in Omics, Computational Models, and Advanced Screening Methods for Drug Safety and Efficacy.

It is imperative to comprehend the mechanisms that underlie drug toxicity in order to enhance the efficacy and safety of novel therapeutic agents. The capacity to identify molecular pathways that contribute to drug-induced toxicity has been significantly enhanced by recent developments in omics technologies, such as transcriptomics, proteomics, and metabolomics. This has enabled the early identification of potential adverse effects.

Redox system and ROS-related disorders in peroxisomes.

Peroxisomes are essential organelles that help mitigate the oxidative damage caused by reactive oxygen species (ROS) through their antioxidant systems. They perform functions such as α-oxidation, β-oxidation, and the synthesis of cholesterol and ether phospholipids. During the breakdown of specific metabolites, peroxisomes generate ROS as byproducts, which can either be neutralized or contribute to oxidative stress.

Effect of Dietary Crude Protein Reduction Levels on Performance, Nutrient Digestibility, Nitrogen Utilization, Blood Parameters, Meat Quality, and Welfare Index of Broilers in Welfare-Friendly Environments.

We investigated the effects of feeding different levels of crude protein (CP) on broiler performance, blood characteristics, meat quality, nutrient and nitrogen (N) availability, stress levels, and welfare indicators in a welfare environment. A total of 625 eight-day-old male broilers were assigned to five dietary CP levels (control (CON) and 1-4% CP reductions) during the grower (8-21 days) and finisher (22-35 days) periods. The CON diet contained 20% CP in the grower phase and 19% in the finisher phase, while all birds received a 22% CP diet during the starter period (1-7 days).
