Spodoptera littoralis Boisduval (Lepidoptera: Noctuidae) and Spodoptera exigua Hübner (Lepidoptera: Noctuidae) pose substantial threats to many crops, necessitating the exploration of biopesticides as potential chemical alternatives. One alternative is baculoviruses; however, their instability in the field has hindered their widespread use. Host plant phylloplane affects baculovirus activity at varying levels in different host plants.

Background: Appropriate management of fractures is crucial for restoring natural bone function and preventing long-term complications. Previous research on animal models indicates that trehalose can improve bone fracture healing by inhibiting the inflammatory cascade. We hope that trehalose can accelerate bone fracture healing in humans, alleviate pain, and ultimately enhance the individual's quality of life.

Article Synopsis
  • Peri-trochanteric fractures are common in older adults with osteoporosis and lead to significant health issues, including pain, immobility, and increased mortality, especially in Nordic countries.
  • The study is a randomized, double-blind trial involving 64 patients to test the effects of trehalose, a sugar with potential wound healing benefits, against a placebo over 12 weeks, monitoring inflammation and healing.
  • Ethical approval has been obtained from Shahid Beheshti University, with the trial registered in the Iranian Clinical Trials database for transparency and accountability.

Osteoporosis is a widespread chronic condition. Although standard treatments are generally effective, they are frequently constrained by side effects and the risk of developing drug resistance. A promising area of research is the investigation of extracellular vesicles (EVs), including exosomes, microvesicles, and apoptotic bodies, which play a crucial role in bone metabolism.

Anterior cruciate ligament (ACL) injuries are prevalent and can have debilitating consequences, with various factors potentially influencing their occurrence. This multicentric study aimed to comprehensively analyze the epidemiological characteristics of ACL injuries. We hypothesized that specific patient characteristics, such as age, sex, body mass index (BMI), and sports involvement, would be associated with distinct injury patterns and risk profiles.

Article Synopsis
  • Rheumatoid arthritis (RA) is an autoimmune disorder characterized by chronic inflammation leading to joint damage, with treatment aimed at reducing inflammation.
  • Traditional medications may have non-specific effects on cell metabolism, prompting interest in specialized pro-resolving mediators (SPMs), which help resolve inflammation and restore tissue health.
  • SPMs are derived from omega-3 fatty acids and their production may be disrupted in RA, highlighting their potential as protective and healing agents in managing the condition.

Background: Osteosarcoma is one of the most common childhood bone malignancies. Although chemotherapy protocol including methotrexate is an effective treatment for osteosarcoma, some other regimens have excluded it because of its complications.

Methods: This retrospective study was conducted on 93 children younger than 15 years old who were diagnosed with osteosarcomafrom March 2007 to January 2020.

Background: Despite the increasing development of different smartphone apps in the health care domain, most of these apps lack proper evaluation. In fact, with the rapid development of smartphones and wireless communication infrastructure, many health care systems around the world are using these apps to provide health services for people without sufficient scientific efforts to design, develop, and evaluate them.

Objective: The objective of this study was to evaluate the usability of CanSelfMan, a self-management app that provides access to reliable information to improve communication between health care providers and children with cancer and their parents/caregivers, facilitating remote monitoring and promoting medication adherence.

The childhood cancer registry in Iran is a hospital-based system and there is not any unique and national registry system for pediatric malignancies in Iran. According to the limitations and requirements, this study was designed to clarify the aspect of childhood malignancies in Iran and promote establishing the Iranian national childhood cancer registry system. This cross-sectional longitudinal study was implied on 1500 patients younger than 20-years old diagnosed with any malignancy and admitted at MAHAK Pediatric Cancer Treatment and Research Center (MPCTRC) from 2007 to 2014.

Introduction: Blunt traumas, like road accidents and falls, are common causes of injuries to pregnant women, and the major risk factors are young age and low socioeconomic level. Due to physiological and anatomical changes specific to pregnancy, such as changes in blood pressure and hemoglobin drop, trauma management involves certain complexities. Physical trauma is estimated to cause at least 1 complication in every 12 pregnancies.

  • The study compares patient and globe survival rates of retinoblastoma (Rb) patients in Tehran, Iran, before and after the introduction of new targeted treatments like intra-arterial and intravitreal chemotherapy.
  • In group 2 (2008-2018), the overall survival rate increased to 99%, and enucleation rates for primary treatment significantly decreased from 50% in group 1 (2001-2007) to 35% in group 2.
  • There were notable improvements in globe survival for advanced retinoblastoma classifications between the two groups, indicating success in the new treatment approaches.

Entomopathogenic fungi produce extracellular enzymes to facilitate host infection, and these can also reduce metal ions to produce nanoparticles. In the present study, three isolates of Beauveria bassiana (JS1, JS2 and KA75) and one isolate of Metarhizium anisopliae (TT1) were evaluated for their ability to biosynthesize silver nanoparticles (AgNPs). In general, the best yields and smallest NP sizes were obtained at 60 °C and pH 7.

Currently, liver transplantation (LT) is considered as the only option for the treatment of patients with various causes of liver failure, including patients with chronic hepatitis B virus (HBV) infections. Overall, patients with HBV who undergo LT are at increased risk of hepatitis B infection recurrence. Although the current knowledge regarding the pathophysiology of this infection has been dramatically increased over the past few decades, it is still considered a complex disease process with varying degrees of clinical characteristics and changing patterns over time.
