Background: Plant fungal pathogens cause substantial economic losses through crop yield reduction and post-harvest storage losses. The utilization of biocontrol agents presents a sustainable strategy to manage plant diseases, reducing the reliance on hazardous chemical. Recently, Pichia kudriavzevii has emerged as a promising biocontrol agent because of its capacity to inhibit fungal growth, offering a potential solution for plant disease management.

According to WHO warnings, the antibiotic resistance crisis is a severe health issue in the 21st century, attributed to the overuse and misuse of these medications. Consequently, the dramatic spreading rate of the drug-resistant microbial pathogens strains. The microbiological, biochemical tests and antibiotic sensitivity identified the bacteria's multi-drug resistance (MDR).

Acute traumatic patellar dislocation is a common injury, and spontaneous reduction may occur at the time of injury or may be reduced at the field of the accident by someone. It may be associated with osteochondral fractures and rupture of medial patellar stabilizers leading to recurrent patellar instability. The aim of this prospective study was to evaluate the outcomes of medial patellofemoral (PF) ligament (MPFL) reconstruction in recurrent traumatic patellar dislocation.

Background: Rotational instability of the knee remains an issue after anterior cruciate ligament (ACL) reconstruction. Hypothesis/Purpose: The purpose was to evaluate the subjective and objective outcomes of combined reconstruction of the ACL and anterolateral ligament (ALL) of the knee. The hypothesis was that favorable outcomes can be achieved with this surgical procedure compared with isolated anatomic reconstruction of the ACL.

Background: Coccydynia can lead to significant functional disability and worsening of quality of life if not properly managed. In this study, we aim to assess the outcomes of extracorporeal shock wave therapy in patients with coccydynia.

Methods: A prospective case series study was carried out from January to December 2015.

Objectives: This study was designed to compare skeletal and dental angular measurements of orthodontic treatment facilitated by cone beam guided corticotomy to that of conventional orthodontic treatment as well as treatment time.

Methods: Twenty female and male adult orthodontic patients with an age range of 19 to 29 years and suffering from bimaxillary protrusion recommended for first premolars extraction were randomly assigned to one of two groups: The test group was treated with a closed technique of corticotomy -facilitated orthodontics using a piezoelectric device and guided by cone beam radiography. The control group was treated with conventional orthodontic treatment.

Background: Anatomic double-bundle anterior cruciate ligament (ACL) reconstruction provides excellent results for restoring normal kinematics to the knee. Nevertheless, strong evidence supporting an ideal method for fixation of the ACL graft is lacking.

Hypothesis: Intratunnel femoral fixation of the ACL graft via a cross-pin fixation technique would provide better clinical and objective results than the extratunnel femoral fixation with cortical buttons.

Purpose: To evaluate the results of our method of surgical treatment of traumatic knee dislocation with injury to the posterolateral corner by use of a standardized protocol.

Methods: Twenty-five consecutive patients presented with a grossly dislocated or reduced knee. Five of these patients were not included in this series.

Aim: To evaluate the effect of bone grafting in corticotomy-facilitated orthodontics in adults, using a further modified conventional corticotomy technique.

Methods: Twenty adult orthodontic patients with moderate crowding of the lower anterior teeth were equally divided into two groups and treated with either a modified corticotomy-faciIitated orthodontic tooth movement alone (Group I) or modified corticotomy-facilitated orthodontic tooth movement combined with bone grafting (Group II). Total treatment time was calculated in weeks from the time of activation of the orthodontic appliance immediately following the corticotomy procedure to the time of debracketing.

Background: Combined orthodontic/regenerative therapy can resolve complex clinical problems and enhance bone formation. The purpose of this study was to evaluate the effectiveness of different times of initiating the active orthodontic tooth movement on the regenerative potential of the intrabony defects.

Methods: Fifteen adult patients with at least three intrabony defects and malocclusion were included.

Background: The aim of this study was to histologically evaluate the effectiveness of different times of initiating orthodontic tooth movement on enhancement of bone formation in surgical bony defects.

Methods: In 18 male guinea pigs, 3-4 months of age, a bony defect was created in the alveolar process midway between the central incisor and mandibular 1st molar. These bony defects were implanted with bioactive glass particles and collagen membrane.

Unlabelled: Chronic Achilles tendon ruptures are often challenging to repair because of muscle and tendon atrophy, retraction, and short distal stumps. We undertook a retrospective investigation of 14 patients who were treated with the Ligament Advanced Reinforcement System (LARS) ligament for the treatment of chronic, neglected rupture of the Achilles tendon. The patients pursued a course of early functional rehabilitation, and postoperative outcome scores were obtained at 3, 6, and 12 months, based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scoring system, and the Tegner Activity score.

Purpose: To evaluate the clinical results of anterior cruciate ligament (ACL) reconstruction in patients with ACL-deficient knee in 2 similar groups of patients.

Type Of Study: A prospective randomized comparison of patellar tendon (PT) versus semitendinosus and gracilis tendon (STG) autografts for ACL reconstruction.

Methods: Between 1994 and 1996, 85 consecutive male patients with chronic ACL-deficient knees underwent arthroscopically assisted reconstruction with either autologous PT or double-loop STG (4-strand) graft.
