Maize drought protection by Azospirillum argentinense Az19 requires bacterial trehalose accumulation.

Azospirillum argentinense Az19 is an osmotolerant plant growth-promoting bacterium that protects maize plants from drought. In this work, we explored the role of trehalose in the superior performance of Az19 under stress. The trehalase-coding gene treF was constitutively expressed in Az19 through a miniTn7 system.

A retrospective comparison of Coronal Plane Alignment of the Knee.

Background: Unicompartmental arthritic degeneration is treated by unicompartmental knee arthroplasties (UKA). The two current standards are mechanical alignment, where knee placement is perpendicular to the leg's mechanical axis and kinematic alignment, that consists of aligning the knee with the angles specific to the patient's innate bone structure. The purpose of this study was to compare knee alignment between mechanical and kinematic UKA.

Altered expression of systemic and ovarian factors involved in the recruitment and activation of immune cells in bovine cystic ovarian disease.

Despite the involvement of both immune cells and soluble factors in the etiopathogenesis of cystic ovarian disease (COD), the precise interplay between these components in this reproductive condition remains unclear. Based on this, in the present study we aimed to evaluate the expression of key molecules involved both locally and systemically in the recruitment, infiltration and activation of immune cells in Holstein cows diagnosed with follicular cysts (N = 5). For this, animals from commercial dairy farms located in the milk-productive region of Santa Fe, Argentina were included after their diagnosis were confirmed by ultrasonographic examination and hormonal evaluation.

Investigating the Influence of Modifiable Physical Measures on the Elbow Varus Torque - Ball Velocity Relationship in Collegiate Baseball Pitchers.

Background: The mechanism of ulnar collateral ligament (UCL) injury during pitching is excessive elbow varus torque (EVT). The EVT-ball velocity (T-V) relationship allows concurrent assessment of player performance and UCL injury risk. Modifiable physical capacities may underlie individual variation seen in the T-V relationship.
