Background: Compost-bedded pack barns (CBP) are getting huge attention as an alternative housing system for dairy cows due to their beneficial impact on animal welfare. Effective microorganisms (EM) inoculums are believed to enhance compost quality, improve soil structure and benefit the environment. However, little information is available on the impact of incubation with external EM combinations on the barn environment, compost quality and microbial diversity in CBP.

Article Synopsis
  • Dietary manipulation, specifically reducing crude protein (CP) while increasing soluble protein (SP) levels, can significantly lower the environmental nitrogen footprints of ruminants like sheep.
  • In a study with 32 male Hu sheep, diets with a 10% reduction in CP and various SP levels resulted in lower plasma nitrogen waste and changes in gut microbiota linked to better energy metabolism.
  • Increased levels of soluble protein (25-30% of CP) led to improved nitrogen absorption and reduced markers of reactive nitrogen production, suggesting a promising approach for optimizing ruminant diets and minimizing environmental impacts.

Domesticated herbivores are an important agricultural resource that play a critical role in global food security, particularly as they can adapt to varied environments, including marginal lands. An understanding of the molecular basis of their biology would contribute to better management and sustainable production. Thus, we conducted transcriptome sequencing of 100 to 105 tissues from two females of each of seven species of herbivore (cattle, sheep, goats, sika deer, horses, donkeys, and rabbits) including two breeds of sheep.

Dietary copper supplementation in the feed of piglets generally exceeds 250-800 mg/kg, where a higher quantity (>250 mg/kg) can promote growth and improve feed conversion. Despite the reported positive effects, 90% of copper is excreted and can accumulate and pollute the soil. Data indicate that fungi have a biosorptive capacity for copper.

Objective: To elucidate the possible mechanism of oral carcinogenesis and to explore the value of clinical application of the detection of cytokeratin (CK) 19 for oral squamous cell carcinoma (OSCC) patients.

Methods: The cancerous tissues, para-cancerous tissues and excised lymph nodes were collected from 20 operated patients with OSCC. The patients didn't receive radiotherapy and chemotherapy before hospitalization.

Objective: To evaluate the feasibility of localizing the internal auditory canal (IAC) and the facial nerve through the root of the zygoma, foramen spinosum and the head of the malleus in middle fossa approach with the assistance of high resolution computerized tomography (HRCT).

Methods: Eighteen human cadaveric temporal bones were scanned and measured by HRCT. Cadaver specimen were divided into two groups.

Objective: To study effect of nimodipine (ND) on cochlear blood flow (CBF).

Method: CBF was measured in twenty-two guinea pigs by laser Doppler flowmetry(LDF).

Result: Nimodipine decreased CBF following the decrease of systemic BP and present a dose dependent mode, neither the dose of nimodipine is lower, normal and higher, nor the animal is under the status of normal supply of inner ear blood flow and ischemia of inner ear caused by vertebrobasilar insufficiency(VBI).
