Human Placenta Hydrolysate Protects Against Acetaminophen-Induced Liver Injury in Mice.

: Acetaminophen (APAP) is a widely used analgesic and antipyretic, but overdose can lead to APAP-induced liver injury (AILI), a major cause of acute liver failure. While N-acetylcysteine (NAC) is the current standard of care, its efficacy is significantly reduced when administered after the peak time of liver injury, highlighting the need for alternative therapeutic strategies. Human placenta hydrolysate (HPH) has shown potential as a therapeutic agent for various liver diseases due to its rich content of bioactive compounds.

Effectiveness of abdominal bracing core exercises as rehabilitation therapy for reducing abdominal symptoms in patients with autosomal dominant polycystic kidney disease and significant polycystic liver disease.

In patients with autosomal dominant polycystic kidney disease (ADPKD) who also have polycystic liver disease (PLD), organomegaly often leads to abdominal symptoms. Abdominal bracing core (ABC) exercises have been validated as effective for alleviating chronic back pain. The purpose of this study was to assess the effectiveness of ABC rehabilitation exercises in reducing pain in ADPKD patients with significant PLD.

Effects of Metabolites Derived from Guava ( L.) Leaf Extract Fermented by on Hepatic Energy Metabolism via SIRT1-PGC1α Signaling in Diabetic Mice.

Background/objectives: Type 2 diabetes mellitus (T2DM) is considered a serious risk to public health since its prevalence is rapidly increasing worldwide despite numerous therapeutics. Insulin resistance in T2DM contributes to chronic inflammation and other metabolic abnormalities that generate fat accumulation in the liver, eventually leading to the progression of metabolic dysfunction-associated fatty liver disease (MAFLD). Recently, the possibility that microbial-derived metabolites may alleviate MAFLD through enterohepatic circulation has emerged, but the underlying mechanism remains unclear.

Analgesic Effect of Human Placenta Hydrolysate on CFA-Induced Inflammatory Pain in Mice.

To evaluate the efficacy of human placenta hydrolysate (HPH) in a mice model of CFA-induced inflammatory pain. TNF-α, IL-1β, and IL-6 are key pro-inflammatory cytokine factors for relieving inflammatory pain. Therefore, this study investigates whether HPH suppresses CFA-induced pain and attenuates the inflammatory process by regulating cytokines.

Evaluation of inhalation risk during quarantine work with quaternary ammonium compounds-based disinfectant.

Quarantine work is widely recognized as an indispensable endeavor in curbing the propagation of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Furthermore, the heavy workload places workers at a heightened risk of chemical exposure and respiratory damage. Consequently, it is paramount to systematically perform health risk assessments and meticulously oversee the work by wearing personal protective equipment to minimize these risks.

Non-contrast low-dose CT can be used for volumetry of ADPKD.

Background: Kidney volume provides important information for the diagnosis and prognosis of autosomal dominant polycystic kidney disease (ADPKD), as well as for the evaluation of the effects of drugs such as tolvaptan. Non-contrast computed tomography (CT) is commonly used for volumetry, and this study examined the correspondence and correlation of kidney volume measured by standard-dose or low-dose CT.

Methods: Axial standard-dose and low-dose CT images with 1-mm slices were obtained from 24 ADPKD patients.

Ultrasmall polymer-coated cerium oxide nanoparticles as a traumatic brain injury therapy.

No medication has been approved for secondary injuries after traumatic brain injury (TBI). While free radicals are considered a major mediator of secondary injury, conventional antioxidants only have modest clinical efficacy. Here, we synthesized CX201 consisting of core cerium oxide nanoparticles coated with 6-aminocaproic acid and polyvinylpyrrolidone in aqueous phase.

The Administration of Panax Ginseng Berry Extract Attenuates High-Fat-Diet-Induced Sarcopenic Obesity in C57BL/6 Mice.

Sarcopenia and obesity are serious health problems that are highly related to several metabolic diseases. Sarcopenic obesity, a combined state of sarcopenia and obesity, results in higher risks of metabolic diseases and even mortality than sarcopenia or obesity alone. Therefore, the development of therapeutic agents for sarcopenic obesity is crucial.

Oyster Hydrolysates Attenuate Muscle Atrophy via Regulating Protein Turnover and Mitochondria Biogenesis in C2C12 Cell and Immobilized Mice.

Sarcopenia, also known as skeletal muscle atrophy, is characterized by significant loss of muscle mass and strength. Oyster (Crassostrea gigas) hydrolysates have anti-cancer, antioxidant, and anti-inflammation properties. However, the anti-sarcopenic effect of oyster hydrolysates remains uninvestigated.

PD-L1/B7-H1 Inhibits Viral Clearance by Macrophages in HSV-1-Infected Corneas.

Immune privilege helps protect the cornea from damaging inflammation but can also impair pathogen clearance from this mucosal surface. Programmed death-ligand 1 (PD-L1 or B7-H1) contributes to corneal immune privilege by inhibiting the function of a variety of immune cells. We asked whether programmed death-1 (PD-1)/PD-L1 interaction regulates HSV-1 clearance from infected corneas.

Broadening the repertoire of functional herpes simplex virus type 1-specific CD8+ T cells reduces viral reactivation from latency in sensory ganglia.

A large proportion of the world population harbors HSV type 1 (HSV-1) in a latent state in their trigeminal ganglia (TG). TG-resident CD8(+) T cells appear important for preventing HSV-1 reactivation from latency and recurrent herpetic disease. In C57BL/6J mice, half of these cells are specific for an immunodominant epitope on HSV-1 glycoprotein B, whereas the other half are specific for 18 subdominant epitopes.

PD-L1/B7-H1 regulates the survival but not the function of CD8+ T cells in herpes simplex virus type 1 latently infected trigeminal ganglia.

HSV type 1 (HSV-1)-specific CD8(+) T cells provide immunosurveillance of trigeminal ganglion (TG) neurons that harbor latent HSV-1. In C57BL/6 mice, the TG-resident CD8(+) T cells are HSV specific and maintain a 1:1 ratio of cells recognizing an immunodominant epitope on viral glycoprotein B (gB498-505-Tet(+)) and cells reactive to subdominant epitopes (gB-Tet(-)). The gB-Tet(-) CD8(+) T cells maintain their frequency in TG by balancing a higher rate of proliferation with a correspondingly higher rate of apoptosis.
