In this study, we investigated if the usually discarded trimmings from dry aged beef can be incorporated into raw fermented sausages as a substitute for fresh beef without altering any major characteristics. Dry aged trimmings were subjected to high-pressure processing (600 MPa, 3 min hold) to reduce the bacterial load, achieving a 3-log reduction. HPP-treated dry aged beef trimmings were then incorporated into raw fermented sausages (60% pork and 40% beef). Beef was substituted with trimmings in different concentrations (7.5, 12.5, 25, 50, 100%). Due to the substitution, the water content of the sausages was reduced depending on the amount of beef substituted. Consequently, the sausages with substituted beef, for example, 50 and 100%, achieved the same water content after 5.4 and 3.7 days, respectively, than control sausage at day 9. However, the substitution (100%) affected the fat content, which contributes to significant differences (p < .05) in firmness during ripening.

Introduction: Bihar Rural Livelihoods Promotion Society launched the JEEViKA program in 2007 to improve livelihoods through the Self-Help Group (SHG) platform. Women's SHGs have shown members' health improvements by promoting awareness, practices and access to services. This study investigates whether Health & Nutrition (HN) interventions delivered by JEEViKA Technical Support Program (JTSP) via SHG platforms could improve maternal and newborn health and nutritional behaviors in rural Bihar.

Powder-based fire extinguishing agents have become a kind of promising substitutes for halon extinguishing agents in civil aircrafts. However, their storage lifespan, significantly influenced by the thermal aging, emerges as a crucial yet overlooked aspect for aviation use. This study investigates the effects of thermal aging cycles on various parameters of ordinary dry powder extinguishing agent (ODPEA) and novel superhydrophobic and oleophobic ultra-fine dry powder extinguishing agent (SHOU DPEA), including surface microscopic morphology, D90 (the diameter at which 90% of the cumulative volume of particles are equal to or smaller than this value), chemical structure, hydrophobic and oleophobic angles, flowability, extinguishing time and effectiveness.

Introduction: Inhalers are critical in asthma treatment, and inappropriate inhaler use leads to poor asthma outcomes. In adults and adolescents, dry powder inhalers (DPIs) are safe and effective alternatives to mainstay pressurised metered dose inhalers and could bridge the asthma care gap while also reducing the environmental burden of asthma care. Despite being licensed for use in ages 5 years old and older, the evidence for clinical effectiveness is less clear for patients between ages 5 and 12 years.

Introduction Dry eye and hyposalivation, often linked to Sjögren's syndrome (SS), are prevalent among adults. However, systemic diseases and their associated medications also play a role, as drug interactions can intensify the effects of certain medications. Objective To assess whether polypharmacy is associated with the co-occurrence of aqueous-deficient dry eye (ADDE) and hyposalivation in adults aged 50 years and older without SS.

This study aimed to investigate the efficacy of inverted door flap (IDF) combined with transcanal approach to the tympanic antrum (TCAA) technique under the endoscope for treatment of middle ear cholesteatoma. Outcomes of patients treated with combined techniques at the First People's Hospital of Foshan City between March 2021 and March 2023 were evaluated. A total of 31 patients (33 ears, 16 males and 15 females) aged (42.
