This study aimed to develop aptamers targeting LipL32, a most abundant lipoprotein in pathogenic Leptospira, to hinder bacterial invasion. The objectives were to identify high-affinity aptamers through SELEX and evaluate their specificity and inhibitory effects. SELEX was employed to generate LipL32 aptamers (L32APs) over 15 rounds of selection.

Article Synopsis
  • BK Polyomavirus (BKPyV) is a common issue for kidney transplant patients, leading to serious complications, and there are currently no effective antiviral treatments.
  • The study explored how Interferon alpha (IFNα) and its induced protein MxA could potentially fight BKPyV using lab experiments and animal models.
  • Results showed that IFNα successfully inhibits BKPyV and that MxA plays a key role in this process by interacting with BKPyV TAg, affecting its localization and ultimately enhancing the antiviral effect.

Programmable metasurfaces present significant capabilities in manipulating electromagnetic waves, making them a promising candidate for simultaneous wireless information and power transfer (SWIPT), which has the potential to enable sustainable wireless communication in complex electromagnetic environments. However, challenges remain in terms of maximum power transmission distance and stable phase manipulation with high-power scattered waves. Additionally, waveform limitations restrict average scattered power and rectifier conversion efficiency, affecting data transmission rates and energy transmission distance.

Renal fibrosis is a common pathway leading to progressive renal function loss in various forms of chronic kidney disease. Many fibrogenic factors regulate renal fibrosis; two key players are post-injury inflammation and transforming growth factor-β1 (TGF-β1)-induced myofibroblast differentiation. Myofibroblast differentiation is tightly regulated by the microtubule polymerization.

Recent studies have suggested that BK polyomavirus (BKPyV) may be associated with the development of urothelial carcinoma. In Merkel cell carcinoma, TAg and tAg are the major viral proteins of Merkel cell polyomavirus with oncogenic potential. In this study, we aimed to distinguish the role of TAg and tAg in cell migration.

In peritoneal dialysis (PD) therapy, intra-abdominal adhesions (IAAs) can cause catheter insertion failure, poor dialysis function, and decreased PD adequacy. Unfortunately, IAAs are not readily visible to currently available imaging methods. The laparoscopic approach for inserting PD catheters enables direct visualization of IAAs and simultaneously performs adhesiolysis.

Leptospirosis can cause chronic kidney damage, putting patients at risk of additional kidney injury due to other factors that can lead to renal failure. To understand the combined effect, the transcriptome profiles of kidneys of mice with adenine-induced and chronically Leptospira-infected kidneys were analysed. Chronic inflammation and T-helper 17 immune responses were activated and a high-level expression of Indoleamine 2,3-dioxygenase 1 protein was found.

Article Synopsis
  • Tuberculous peritonitis (TBP) is a serious and uncommon condition that can occur in patients undergoing peritoneal dialysis, with this study examining the characteristics and outcomes of affected patients from a large cohort.
  • Out of 2084 patients studied, 18 were diagnosed with TBP, most commonly showing symptoms like fever, cloudy effluent, and abdominal pain; half had low white blood cell counts in their peritoneal fluid.
  • The study found that although significant factors such as sex, diabetes, and PD catheter removal were associated with mortality risks, they were not determinative in predicting 1-year mortality, highlighting the need for early diagnosis and proper treatment.

Introduction: Fluid overload is an unavoidable problem in patients on peritoneal dialysis (PD) and is associated with poor outcomes. The aim of our study was to estimate ultrafiltration (UF) under different dextrose concentrations (DCs) and four peritoneal transport levels.

Materials And Methods: 70 patients, with a total of 1,848 daily treatment records and 8,266 single dwells on automated PD (APD) through Homechoice Claria with Sharesource were followed in October 2020 and categorized into two groups according to the DC (D1.

The aberrant activation of the purinergic signaling pathway has been shown to promote cyst growth and fluid secretion in autosomal dominant polycystic kidney disease (ADPKD). Suramin is an anti-parasitic drug that has strong anti-purinergic properties. Whether suramin could have a therapeutic effect on ADPKD has not been fully investigated.

Leptospirosis, an emerging infectious disease caused by pathogenic spp., occurs in ecoregions with heavy rainfall and has public health implications. Macrophages are the major anti- phagocytes that infiltrate the kidneys during renal leptospirosis, which is caused by leptospires residing in the renal tubules.

Metabolic reprogramming is a potential treatment strategy for autosomal dominant polycystic kidney disease (ADPKD). Metformin has been shown to inhibit the early stages of cyst formation in animal models. However, metformin can lead to lactic acidosis in diabetic patients with advanced chronic kidney disease, and its efficacy in ADPKD is still not fully understood.

Approximately 1 million cases of leptospirosis, an emerging infectious zoonotic disease, are reported each year. Pathogenic species express leucine-rich repeat (LRR) proteins that are rarely expressed in non-pathogenic species. The LRR domain-containing protein family is vital for the virulence of pathogenic species.

Beta-hydroxybutyric acid (BHB) exerts a protective effect in experimental of kidney disease models. However, the mechanisms underlying this activity are not well defined. BHB stands out for its ability to inhibit the Nε-lysine acetylation of histone and non-histone proteins, which may affect cellular processes and protein functions.

In leading the high-quality development of Chinese medicine preparations, it is an important link to formulate the scientific, reasonable, and feasible guidelines for the change of Chinese medicines in accordance with the change characteristics and principles of the Chinese medicines is an important work to promote the Technical guidelines for the study of pharmaceutical changes in traditional Chinese medicines was formed by a broad consensus based on the characteristics and research results of the pharmaceutical changes in Traditional Chinese Medicines(TCM)with the principles of science and risk management. This guideline has clarified the basic principles and requirements for the evaluation of changes in TCM, specified the research and verification work of common change scenarios, defined the boundaries of changes in TCM, and proposed to encourage the use of new technologies, new methods, and new excipients that meet product characteristics. It will definitely promote the quality improvement and the secondary development of TCM.

Article Synopsis
  • Intradialytic hypotension (IDH) adversely affects patients undergoing hemodialysis, leading to poorer quality of life and higher cardiovascular mortality.
  • The study examined 70 end stage renal disease patients to identify autonomic nerve and cardiovascular factors associated with two types of IDH: IDH-f, which involves symptomatic drops in blood pressure, and IDH-n, characterized by low blood pressure without symptoms.
  • Findings highlighted that lower central pulse pressure can predict IDH for both definitions, while lower sympathetic activity and higher augmentation index were associated specifically with IDH-f, and lower mean arterial pressure was linked to IDH-n.

Leptospirosis is an overlooked zoonotic disease caused by pathogenic Leptospira depended on virulence of Leptospira and the host-pathogen interaction. Kidney is the major organ infected by Leptospira which causes tubulointerstitial nephritis. Leptospira outer membrane contains several virulence factors and an outer membrane protein A (OmpA) like protein (Loa22) is essential for virulence.
