Background: Poultry red mites, or , pose a threat to the welfare and productivity of laying hens. Moreover, the increasing resistance of these mites to conventional miticides highlights the urgent need for alternative treatment options. There are also documented cases of poultry red mite infestations in humans.

Vitiligo is a chronic depigmenting condition that causes amelanotic macules and patches on the skin. Despite various treatment options, treating vitiligo is a challenge. This study aimed to evaluate the combination of laser CO fractional and narrow-band ultraviolet B (NB-UVB) versus NB-UVB monotherapy in vitiligo patients.

Diffuse alveolar hemorrhage (DAH), a rare complication of coexisting antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE), poses significant diagnostic and therapeutic challenges, especially with recurrent episodes. We present a 27-year-old male with catastrophic APS and SLE who experienced acute respiratory failure and hemoptysis due to DAH. Despite aggressive therapy with immunosuppressants, plasma exchange, and anticoagulation, he had recurrent DAH episodes requiring repeated admissions.

Article Synopsis
  • - Actinic prurigo is a rare skin condition that causes itchy, raised lesions and is particularly difficult to treat, especially in children.
  • - Effective management requires strict sun protection, as symptoms can last for most of the year.
  • - A case study of an 8-year-old patient showed quick improvement of symptoms using baricitinib, a medication not commonly used for this condition.

Melanoma is responsible for most skin cancer-associated deaths globally. The progression of melanoma is influenced by a number of pathogenic processes. Understanding the VEGF/VEGFR axis, which includes VEGF-A, PlGF, VEGF-B, VEGF-C, and VEGF-D and their receptors, VEGFR-1, VEGFR-2, and VEGFR-3, is of great importance in melanoma due to its crucial role in angiogenesis.

Article Synopsis
  • - The review discusses the role of brain-derived neurotrophic factor (BDNF) in cancer, highlighting its potential to promote cancer cell growth and migration through specific receptor pathways like TrkB and p75NTR.
  • - Studies show that BDNF is overexpressed in several cancers ( prostate, lung, and breast), which is associated with poorer patient outcomes, suggesting that measuring BDNF levels could help in disease diagnosis and treatment response prediction.
  • - Current clinical research is focused on targeting BDNF receptors and their signaling pathways with various agents to potentially mitigate their oncogenic effects, but further trials are needed to thoroughly understand BDNF's role in cancer and explore it as a therapeutic target.

Glass-forming ability (GFA) of bulk metallic glasses (BMGs) is a determinant parameter which has been significantly studied. GFA improvements could be achieved through trial-and-error experiments, as a tedious work, or by using developed predicting tools. Machine-Learning (ML) has been used as a promising method to predict the properties of BMGs by removing the barriers in the way of its alloy design.

Acinetobacter baumannii is a common causative agent of nosocomial infections, with a mortality rate of 43% in infected patients. Due to the emergence of multidrug-resistant (MDR) strains, vaccine development has become necessary. Since the 34 kDa outer membrane protein Omp34 has been identified as a potential vaccine target, we implemented a hybrid antigen approach to target its extracellular loops.

Article Synopsis
  • Glioblastoma (GBM) is the most common type of brain tumor in adults, characterized by a very low survival rate of less than 7% over five years.
  • Current treatments focusing on specific cell metabolism have largely failed to improve patient outcomes.
  • Understanding the intricate communication between GBM cells and their surrounding environment could lead to new therapeutic strategies and improve prognosis for patients.

Breast cancer [BC] is one of the most common cancers among women, one of the leading causes of a considerable number of cancer-related death globally. Among all procedures leading to the formation of breast tumors, angiogenesis has an important role in cancer progression and outcomes. Therefore, various anti-angiogenic strategies have been developed so far to enhance treatment's efficacy in different types of BC.

The process of material cutting emerges from a series of nonlinear phenomena including frictional contact, plastic deformation, and fracture. While cutting dominated by shear deformation is of interest to achieve a smooth material removal and a high-quality surface finish, the fracture-induced chip breaking is of equal importance to prevent the formation of long chips. Here we show that discrepant observations and predictions of these two distinct cutting mechanisms can be reconciled into a unified framework.

Background: Avian metapneumovirus (aMPV) infection has significant economic impacts on the poultry industry all around the world.

Aims: The aim of this study is molecular investigations of different types of aMPV in broiler farms in different provinces of Iran from 2016 to 2018.

Methods: Tracheal and oropharyngeal swabs were collected from two hundred broiler chickens with respiratory signs in ten provinces of Iran, including Kurdistan, West Azerbaijan, Semnan, Esfahan, Sistan and Baluchistan, Qazvin, Khuzestan, Fars, Gilan, and Khorasan Razavi from February 2016 to December 2018.

Background: Evidence recommends that vitamin D might be a crucial supportive agent for the immune system, mainly in cytokine response regulation against COVID-19. Hence, we carried out a systematic review and meta-analysis in order to maximise the use of everything that exists about the role of vitamin D in the COVID-19.

Methods: A systematic search was performed in PubMed, Scopus, Embase and Web of Science up to December 18, 2020.

Adaptation to the loss of O2 is regulated via the activity of hypoxia-inducible factors such as Hypoxia-Inducible Factor-1 (HIF-1). HIF-1 acts as a main transcriptional mediator in the tissue hypoxia response that regulates over 1000 genes related to low oxygen tension. The role of HIF-1α in oncogenic processes includes angiogenesis, tumor metabolism, cell proliferation, and metastasis, which has been examined in various malignancies, such as melanoma.

Since 1998, Iran's poultry industry has faced several outbreaks of low pathogenic avian influenza H9N2. Tissue samples were collected from a broiler flock with respiratory symptoms in autumn 2017. After that, virus isolation and confirmation of H9N2 using RT-PCR, sequencing, and bioinformatic analysis for all eight genes were performed.

Infectious bronchitis (IB) is an acute, highly contagious, and economically important viral disease of chickens. The S1 subunit from Spike (S) protein plays the major role in protective immunity and is involved in the host-virus interactions, as well as infectious bronchitis virus (IBV) serotyping. Aim of the present study was multi-aspect analysis of the molecular and immunological features of 5' part belonging to the S1 glycoprotein sequence of Iranian 793/B IBV strain isolates.

Background: Infection in pediatric cancer patients has become a concerning problem due to increasing antimicrobial resistance. The goal of this study was to determine the antimicrobial resistance patterns of blood isolates from pediatric oncology patients in Iran to determine if there was significant resistance to quinolones.

Methods: Children with cancer who were admitted with or developed fever during admission to Aliasghar Children's Hospital or Mahak Hospitals July 2009 through June 2011 were eligible for enrollment.
