Bovine whey protein has been demonstrated to exert a positive effect on energy balance, lipid metabolism, and nutrient absorption. Additionally, it affects gut microbiota configuration. Thus, whey protein is considered as good dietary candidate to prevent or ameliorate metabolic diseases, such as obesity. However, the relationship that links energy balance, metabolism, and intestinal microbial population mediated by whey protein intake remains poorly understood. In this study, we investigated the beneficial effects attributed to whey protein in the context of high-fat diet (HFD) in mice at two different ages, with short or longer durations of whey protein supplementation. Here, a 5-week dietary intervention with HFD in combination with either whey protein isolate (WPI) or the control nonwhey milk protein casein (CAS) was performed using 5-week or 10-week-old C57BL/6J mice. Notably, the younger mice had no prior history of ingestion of WPI, while older mice did. 5-week-old HFD-WPI-fed mice showed a decrease in weight gain and changes in the expression of genes within the epidydimal white adipose tissue including those encoding leptin, inflammatory marker CD68, fasting-induced adipose factor FIAF and enzymes involved in fatty acids catabolism, relative to HFD-CAS-fed mice. Differences in β-diversity and higher proportions of Lactobacillus murinus, and related functions, were evident within the gut microbiota of HFD-WPI mice. However, none of these changes were observed in mice that started the HFD dietary intervention at 10-weeks-old, with an extended period of WPI supplementation. These results suggest that the effect of whey protein on mouse body weight, adipose tissue, and intestinal parameters depends on diet duration and stage of life during which the diet is provided. In some instances, WPI influences gut microbiota composition and functional potential, which might orchestrate observed metabolic and physiological modifications.Adenovirus infection is commonly associated with self-limited respiratory and gastrointestinal illnesses. However, infection in immunocompromised individuals, such as transplant recipients, can cause severe life-threatening illness including pneumonitis, hemorrhagic cystitis, nephritis, hepatitis, and enterocolitis. In orthotopic liver transplant recipients, adenovirus viremia can cause hepatitis leading to marked transaminitis, allograft loss, and death. Although hepatic abscesses mediated by adenovirus have been described in other immunosuppressed patient populations, it has very rarely been described in liver transplant recipients. Here, we report two adult cases of hepatic abscesses following liver transplantation secondary to adenovirus infection and describe the successful treatment of these patients. Adenovirus should be considered as an uncommon etiology of hepatic abscess and unexplained fevers in adults following liver transplantation.Poly(l-lactic) acid (PLLA) is widely used in guided bone regeneration membranes due to its mechanical properties and biodegradability. However, the lack of biocompatibility is a serious disadvantage. Herein, the biocompatibility of PLLA is improved by patterning hydroxyapatite (HA) loaded with recombinant human bone morphogenetic protein-2 (rhBMP-2) under it. The HA is obtained by preparing a magnesium pattern via photolithography and hydrothermal converting. After loading rhBMP-2, the pattern is transferred to PLLA. The pattern is tightly embedded in the PLLA and retained its original position after mechanical stimuli. Fluorescence images allow to assess the protein adsorption and gradual release in a controlled manner. The amount of released rhBMP-2 is overwhelmingly large when loaded under HA because of its large surface area. Osteogenic differentiation supports the synergistic effect of HA and rhBMP-2 to improve the biocompatibility. Moreover, in vivo experiments demonstrate that the synergistic effect positively affects the healing rate of bone.The GntR family regulators are widely distributed in bacteria and play critical roles in metabolic processes and bacterial pathogenicity. In this study, we describe a GntR family protein encoded by PA4132 that we named MpaR (MvfR-mediated PQS and anthranilate regulator) for its regulation of Pseudomonas quinolone signal (PQS) production and anthranilate metabolism in Pseudomonas aeruginosa. The deletion of mpaR increased biofilm formation and reduced pyocyanin production. RNA sequencing analysis revealed that the mRNA levels of antABC encoding enzymes for the synthesis of catechol from anthranilate, a precursor of the PQS, were most affected by mpaR deletion. Data showed that MpaR directly activates the expression of mvfR, a master regulator of pqs system, and subsequently promotes PQS production. Accordingly, deletion of mpaR activates the expression of antABC genes, and thus, increases catechol production. We also demonstrated that MpaR represses the rhl quorum-sensing (QS) system, which has been shown to control antABC activity. These results suggested that MpaR function is integrated into the QS regulatory network. Moreover, mutation of mpaR promotes bacterial survival in a mouse model of acute pneumonia infection. Collectively, this study identified a novel regulator of pqs system, which coordinately controls anthranilate metabolism and bacterial virulence in P. aeruginosa.Antibody-dependent cellular cytotoxicity (ADCC) is the primary mechanism of actions for several marketed therapeutic antibodies (mAbs) and for many more in clinical trials. The ADCC efficacy is highly dependent on the ability of therapeutic mAbs to recruit effector cells such as natural killer cells, which induce the apoptosis of targeted cells. The recruitment of effector cells by mAbs is negatively affected by fucose modification of N-Glycans on the Fc; thus, utilization of afucosylated mAbs has been a trend for enhanced ADCC therapeutics. Most of afucosylated mAbs in clinical or commercial manufacturing were produced from Fut8-/- Chinese hamster ovary cells (CHO) host cells, generally generating low yields compared to wildtype CHO host. This study details the generation and characterization of two engineered CHOZN® cell lines, in which the enzyme involved in guanosine diphosphate (GDP)-fucose synthesis, GDP mannose-4,6-dehydratase (Gmds) and GDP-L-fucose synthase (FX), was knocked out. The top host cell lines for each of the knockouts, FX-/- and Gmds-/-, were selected based on growth robustness, bulk MSX selection tolerance, production titer, fucosylation level, and cell stability. We tested the production of two proprietary IgG1 mAbs in the engineered host cells, and found that the titers were comparable to CHOZN® cells. The mAbs generated from either KO cell line exhibited loss of fucose modification, leading to significantly boosted FcγRIIIa binding and ADCC effects. Our data demonstrated that both FX-/- and Gmds-/- host cells could replace Fut8-/- CHO cells for clinical manufacturing of antibody therapeutics.Selective androgen receptor modulators (SARMs) are compounds with specific androgenic properties investigated for the treatment of conditions such as muscle wasting diseases. The reported androgenic properties have resulted in their use by athletes, and consequently they have been on the World Anti-Doping Agency prohibited list for more than a decade. SARMs have been investigated by pharmaceutical companies as potential drug candidates, but to date no SARM has demonstrated sufficient safety and efficacy to gain clinical approval by either the European Medicines Agency or the U.S. Food and Drug Administration. Despite their lack of safety approval, SARMs are often illegally marketed as dietary supplements, available for consumers to buy online. In this study, a range of supplement products marketed as SARMs were purchased and analyzed using high resolution accurate mass - mass spectrometry to evaluate the accuracy of product claims and content labeling. This study found discrepancies ranging from a supplement in which no active ingredients were found, to supplements containing undeclared prohibited analytes. Ac-DEVD-CHO purchase Where SARMs were detected, discrepancies were observed between the concentrations measured and those detailed on the product packaging. The outcome of this experiment highlights the high risk of such supplement products to consumers. The inaccurate product claims give rise to uncertainty over both the dose taken and the identity of any of these unapproved drugs. Even for supplements for which the product labeling is correct, the lack of complete toxicity data, especially for combinations of SARMs taken as stacks, means that the safety of these supplements is unknown.
Lower respiratory tract infection (LRTI) is a frequent cause of dyspnoea in EDs, and is associated with considerable morbidity and mortality. We described and compared the management of this disease in Europe and Oceania/South-East Asia (SEA) cohorts.

We conducted a prospective cohort study with three time points in Europe and Oceania/SEA. We included in this manuscript patients presenting to EDs with dyspnoea and a diagnosis of LRTI in ED. We collected comorbidities, chronic medication, clinical signs at arrival, laboratory parameters, ED management and patient outcomes.

A total of 1389 patients were included, 773 in Europe and 616 in SEA. The European cohort had more comorbidities including chronic heart failure, obesity, chronic obstructive pulmonary disease and smoking. Levels of inflammatory markers were higher in Europe. There were more patients with inflammatory markers in Europe and more hypercapnia in Oceania/SEA. The use of antibiotics was higher in SEA (72.2% vs 61.8%, P < 0.001) whereas intravenous diuretics, non-invasive and invasive ventilation were higher in Europe. Intensive care unit admission rate was 9.9% in Europe cohort and 3.4% in Oceania/SEA cohort. ED mortality was 1% and overall in-hospital mortality was 8.7% with no differences between regions.

More patients with LRTI in Europe presented with cardio-respiratory comorbidities, they received more adjunct therapies and had a higher intensive care unit admission rate than patients from Oceania/SEA, although mortality was similar between the two cohorts.

In particular, single-use bags made from multi-layered polymeric films have been adopted for cell culture and liquid handling operations in place of traditional stainless-steel systems. Despite the advantages, leachable compounds originating from the film's materials of construction present a new challenge. In 2013, bis(2,4-di-tert-butylphenyl)phosphate (bDtBPP) was identified as a common leachable from several single-use bags that is detrimental to the growth and viability of many Chinese hamster ovary (CHO) cell lines. While much work has been completed to characterize CHO cell sensitivity to bDtBPP, little has been done to characterize its impact on other important production cell lines, particularly PER.C6®. This publication investigates inconsistent cell growth observed in a PER.C6® cell line during bioprocess development. The growth inhibition was linked to leachable migration from Bioclear™ 10, a single-use film from Cytiva (formerly GE Healthcare) that was used for cell expansion.
