Influence of Single Dose Enrofloxacin Injection on Development of Fluoroquinolone Resistance in in Calves.

Fluoroquinolone (FQ) resistance in a major foodborne bacterial pathogen, , derived from cattle has recently become prevalent and poses a significant public health concern. However, the underlying factors for this increase are not entirely clear.

Mastitis in Dairy Cattle: Etiology, Diagnosis, and Treatment Challenges.

Bovine mastitis is an inflammation of the udder tissue parenchyma that causes pathological changes in the glandular tissue and abnormalities in milk leading to significant economic losses to the dairy industry across the world. Mammary pathogenic (MPEC) is one of the main etiologic agents of acute clinical mastitis in dairy cattle. MPEC strains have virulence attributes to resist the host innate defenses and thrive in the mammary gland environment.

Crisis Response as a Human Rights Flashpoint: Critical Elements of Community Support for Individuals Experiencing Significant Emotional Distress.

This paper proposes a set of nine critical elements underpinned by human rights principles to support individuals experiencing a serious crisis related to mental health problems or psychosocial disabilities. These elements are distilled from a range of viable alternatives to traditional community mental health approaches and are linked to a normative human rights framework. We argue that crisis response is one of the areas of mental health care where there is a heightened risk that the rights of service recipients may be infringed.

Comparison of two anorganic bovine bone in maxillary sinus lift: a split-mouth study with clinical, radiographical, and histomorphometrical analysis.

Background: Anorganic bovine bone (Bio-Oss®) has been extensively used for reconstruction of posterior area of maxilla in sinus lift procedure; however, a new graft material (Lumina-Bone Porous®), that has a different manufacturing process, has not been yet compared in clinical and histological terms. The manufacturing process of bovine bone graft is related to size and porosity of the particles, and this can change osteoconductive property of the material and bone formation. The use of Lumina-Porus® could improve bone formation, reduce the remaining particles of the biomaterial using a low-cost material.
