Development of BCMA-Targeted Bispecific Natural Killer Cell Engagers for Multiple Myeloma Treatment.

Background: B-cell maturation antigen (BCMA)-targeted T cell-redirecting immunotherapies, including Chimeric Antigen Receptor (CAR) T-cell therapy and T-cell engagers have demonstrated remarkable success in treating relapsed/refractory (RR) multiple myeloma (MM), a malignancy of plasma cells. However, a significant challenge is the severe side effects associated with T-cell overactivation, leading to cytokine release syndrome and neurotoxicity in MM patients undergoing such therapies. Bispecific NK cell engagers (NKCEs) may offer a promising alternative by redirecting NK cell cytotoxic activity towards tumor cells without triggering cytokine release syndrome.

Critical appraisal of clinical practice guidelines for otitis media in Asian and Western countries with consideration of updates: A narrative review.

Introduction: Acute otitis media is a common disease in children under the age of 5 years due to their primitive ear anatomy. One of its consequences is otitis media with effusion (OME), which is a condition wherein serous secretion accumulates in the middle ear due to Eustachian tube dysfunction. OME results in conductive hearing loss, impacting children's learning and development.

Late gestation maternal infection with bovine viral diarrhea virus impacts offspring feedlot performance, digestion, blood parameters, and hot carcass weights.

Fetal infection with bovine viral diarrhea virus (BVDV) after 150 d results in transient fetal infections (TI). Twenty-five unvaccinated, yearling Hereford heifers, seronegative for antibodies to BVDV1 and BVDV2, were bred by artificial insemination with X chromosome-bearing sperm from 1 Angus sire to examine the impact of TI on postnatal growth, estimated dry matter digestibility, blood parameters, and carcass characteristics. On day 175 of pregnancy, dams were intranasally inoculated with either sham control or 4.

DBPR116, a Prodrug of BPRMU191, in Combination with Naltrexone as a Safer Opioid Analgesic Than Morphine via Peripheral Administration.

The development of opioid analgesics with reduced adverse effects is an unmet need. In a previous study, we discovered a unique combination of BPRMU191 and morphinan antagonists that produced potent antinociception with reduced adverse effects after central administration (intrathecal or intracerebroventricular). BPRMU191/naltrexone exhibits notable and pharmacological properties.

Trace mineral sources influence in vitro fermentation characteristics and trace mineral solubility.

Two experiments were conducted to determine: 1) the impact of strained rumen fluid (SRF) alone or SRF with particle-associated microorganisms (PAO) included and dilution on in vitro dry matter digestibility (DMD) and 2) the impact of trace mineral (TM) source on in vitro fermentation characteristics and TM solubility under simulated abomasal and intestinal conditions. In experiment 1, 3 cannulated steers were adapted to a diet formulated to meet the nutrient requirements for lactating dairy cows. Strained RF was obtained by straining rumen content through 2 layers of cheesecloth.
