Cyclic Osmate Esters from 1,2- and 1,3-Diols and α-Hydroxy Acids for X-ray Analysis.

We previously demonstrated that osmium tetroxide and TMEDA generate stable crystalline adducts with alkenes that facilitate X-ray analysis and structure assignments. Alternatively, osmate esters can be prepared from diols, potassium osmate, and TMEDA·2TsOH in a nonoxidative condensation reaction. This new approach provides a convenient route to form stable, crystalline osmate(VI) esters for X-ray analysis.

Targeting Astrogliosis in the Retrotrapezoid Nucleus: A Novel Approach to Ameliorate Respiratory Dysfunction and Alzheimer's Pathology in Mice.

Alzheimer's disease (AD), a leading cause of dementia, is associated with significant respiratory dysfunctions. Our study explores the role of astrogliosis in the brainstem retrotrapezoid nucleus (RTN), a key breathing regulatory center, and its impact on breathing control and AD pathology in mice. Using Tg-2576 AD and wild-type mice, we investigated the effect of silencing the transforming growth factor-beta receptor II (TGFβR II) in the RTN.

Optimized synthesis of biphasic calcium phosphate: enhancing bone regeneration with a tailored β-tricalcium phosphate/hydroxyapatite ratio.

Biphasic calcium phosphate (BCP) is a bioceramic widely used in hard tissue engineering for bone replacement. BCP consists of β-tricalcium phosphate (β-TCP) - a highly soluble and resorbable phase - and hydroxyapatite (HA) - a highly stable phase, creating a balance between solubility and resorption, optimally supporting cell interactions and tissue growth. The β-TCP/HA ratio significantly affects the resorption, solubility, and cellular response, with a higher β-TCP ratio increasing resorption due to its solubility.

Influential Factors in the Treatment of Infections at a Tertiary Hospital in Vietnam.

As an opportunistic pathogen, is often associated with severe respiratory infections. A study conducted in an ICU of a tertiary hospital in Vietnam, where infection management is relatively good, yielded only 18 clinical isolates of over 6 months. Though the number is small, treating infections is highly complicated.

Totally endoscopic mitral valve repair with novel technique of left atrial exposure: five years experience from a single center.

Determining the Efficacy of Chemicals for the Inactivation of Liquid Waste Containing Gram-Positive Bacteria of Risk Group 2.

Background: Inactivation of infectious liquid waste can be performed by different means, including autoclaving or chemical inactivation. Autoclaving is most widely used, but cannot always be implemented, so that chemical inactivation is a possible alternative. However, its efficacy has to be proven by in-house validation.

Extracts for Cosmetic Applications: Systematic Review and Meta-Analysis.

We have conducted a systematic review and meta-analysis to evaluate the cosmetic applications of extracts (DMEs). A total of 261 articles were screened; however, after eliminating inappropriate studies, only 16 individual studies were eligible. The comparative standardized mean difference (SMD) between the DME treatment and control groups was used to evaluate the cosmetic properties of DME, including its biocompatibility, whitening effects, and anti-inflammatory and antimicrobial properties.

Enhancing the quality and consumer satisfaction of dragon fruit beverage production: The effects of geological origin and processing conditions.

Objectives: In this study, the impacts of various processing parameters on the quality and consumer satisfaction of dragon fruit beverages were investigated in order to establish an informative framework for the manufacturing of commercial dragon fruit beverages, focusing on health benefits and safety for consumers, and sensory appeal of the products.

Methods: This study employed various analytical methods to quantify some important phytochemical compounds in dragon fruit juice such as total and reducing sugars, vitamin C, betacyanins, anthocyanins, polyphenol, and so forth. This study also employed the Box-Behnken response surface experimental design to optimize various processing parameters for quality and consumer satisfaction, which include enzymatic pectin hydrolysis parameters and formulation for dragon fruit energy drink.

Minimally invasive management of intramural pregnancy using ultrasound combined with laparoscopy -based learning experience from a low-middle income country: a case report and review of the literature.

Background: Intramural pregnancy is a very rare type of ectopic pregnancy, which is surrounded by uterine myometrium layer and separates from endometrium. To our knowledge, this abnormal location site of ectopic pregnancy remains likely under-recognized and under-reported. Through this paper, we aim to underscore the role of minimally invasive surgery in this uncommon condition where applicable, especially in low-middle income countries.

MR1 presents vitamin B6-related compounds for recognition by MR1-reactive T cells.

The major histocompatibility complex class I related protein (MR1) presents microbially derived vitamin B2 precursors to mucosal-associated invariant T (MAIT) cells. MR1 can also present other metabolites to activate MR1-restricted T cells expressing more diverse T cell receptors (TCRs), some with anti-tumor reactivity. However, knowledge of the range of the antigen(s) that can activate diverse MR1-reactive T cells remains incomplete.

Enhancing the porosity of biphasic calcium phosphate using polyethylene glycol as the porogen for bone regeneration applications.

Biphasic calcium phosphate (BCP) has been used as a material to support bone grafting, repair, recovery, and regeneration over the past decades. However, the inherent weakness of BCP is its low porosity, which limits the infiltration, differentiation, and proliferation of bone cells. To address this issue, porous BCP was synthesized using polyethylene glycol (PEG) 1000 with weight ratio ranging from 20%-60% in BCP as the porogen through the powder-forming method.

Levels of high-sensitive troponin T and mid-regional pro-adrenomedullin after COVID-19 vaccination in vulnerable groups: monitoring cardiovascular safety of COVID-19 vaccination.

Background: COVID-19 vaccines are well tolerated and effective but may have adverse effects on the cardiovascular system. Vaccine-associated myocardial injury was analysed by measuring high-sensitive troponin T (hsTnT); mid-regional pro-adrenomedullin (MR-proADM) levels were evaluated to assess endothelial dysfunction.

Methods: This was a prospective study with a vulnerable population of healthcare workers (HCWs) and elderly patients (>70 years) who were vaccinated with either one dose of ChAdOx1 nCov-19 adenoviral vector vaccine (AZ) followed by one dose of the BNT162b2 messenger RNA vaccine (BNT), or with two doses of BNT (12th of January - 30th of November 2021).

Unraveling the architecture of major histocompatibility complex class II haplotypes in rhesus macaques.

The regions in the genome that encode components of the immune system are often featured by polymorphism, copy number variation, and segmental duplications. There is a need to thoroughly characterize these complex regions to gain insight into the impact of genomic diversity on health and disease. Here we resolve the organization of complete major histocompatibility complex (MHC) class II regions in rhesus macaques by using a long-read sequencing strategy (Oxford Nanopore Technologies) in concert with adaptive sampling.

Lipid Nanoparticles Elicit Reactogenicity and Sickness Behavior in Mice Via Toll-Like Receptor 4 and Myeloid Differentiation Protein 88 Axis.

mRNA therapeutics encapsulated in lipid nanoparticles (LNPs) offer promising avenues for treating various diseases. While mRNA vaccines anticipate immunogenicity, the associated reactogenicity of mRNA-loaded LNPs poses significant challenges, especially in protein replacement therapies requiring multiple administrations, leading to adverse effects and suboptimal therapeutic outcomes. Historically, research has primarily focused on the reactogenicity of mRNA cargo, leaving the role of LNPs understudied in this context.
