Salinity inhibits the uptake of nitrogen, which slows down the growth and prevents plant reproduction. Certain ions, especially chloride, are poisonous to plants; when their concentration increases, the plant becomes poisoned and eventually perishes. The adaptability of several table beet cultivars ( L.

Background: Intra-ductal cancer (IDC) is the most common type of breast cancer, with intra-lobular cancer (ILC) coming in second. Surgery is the primary treatment for early stage breast cancer. There are now irrefutable data demonstrating that the immune context of breast tumors can influence growth and metastasis.

Background: There are persistent controversies about the outcomes and benefits of drainage of malignant ureteral obstruction by percutaneous nephrostomy (PCN). This study aimed to assess the predictors of the time-to-nadir (TTN) of serum creatinine (SCr) levels after drainage of bilaterally obstructed kidneys (BOKs) due to bladder cancer (BC) by PCN.

Materials And Methods: This prospective nonrandomized study included patients with BOKs due to BC treated by PCN between April 2019 and March 2022.

Introduction: The spleen is a responsible significant part of the immune system; after Splenectomy following trauma, the immune system changes; splenic autotransplantation can preserve the immune system after trauma and Splenectomy.

Background: Patients can be protected from immune dysfunction by autotransplanting splenic tissues after splenectomy following trauma because their immune systems and spleens are changed. Patients can gain their immune function after splenic autotransplantation.

Background: Numerous surgical techniques are available for the correction of isolated ventral congenital penile curvature (IVCPC). This study aimed to assess the outcomes and predictors of IVCPC treatment in adults using an incisionless plication technique.

Materials And Methods: This prospective case series examined patients with IVCPC who were treated in our hospital between October 2017 and February 2020 using incisionless plication of the tunica albuginea (Essed-Schroeder technique) with a covering pair of absorbable sutures.

Article Synopsis
  • The study focused on three species of the genus Solanum found in Egypt, which are morphologically similar, prompting the need for alternative identification methods.
  • Researchers conducted anatomical, ecological, and molecular analyses, including DNA sequencing and gas chromatography-mass spectrometry (GC-MS) to characterize these species.
  • Findings revealed variations in the anatomical features, molecular sequences, and chemical profiles of the species, with 38 compounds identified, aiding in their chemical identification.

Plant diseases are biotic stresses that restrict crop plants' ability to develop and produce. Numerous foliar diseases, such as chocolate spots, can cause significant production losses in plants. Certain chemical inducers, including salicylic acid (SA), oxalic acid (OA), nicotinic acid (NA), and benzoic acid (BA), were used in this study to assess efficacy in controlling these diseases.

Background: Serum creatinine trajectory (SCr-Tr) is a neglected prognostic tool for chronic and acute kidney injury. We aimed to assess the predictors of SCr-Tr during the time-to-nadir and serum creatinine (SCr) normalization rate after drainage, using percutaneous nephrostomy in patients with bilateral malignant ureteral obstruction.

Methods: A prospective non-randomized study was performed on SCr-Tr in patients with bilateral malignant ureteral obstruction from August 2019 to March 2022.

Article Synopsis
  • - The study emphasizes the importance of verifying taxonomic identities in biology, using a combined approach of morphological and molecular characterization to distinguish among five local taxa of a specific genus.
  • - Variations in leaf and cypsela characteristics were noted under Mediterranean conditions, and a phylogenetic analysis revealed different groupings among the examined taxa.
  • - Molecular markers demonstrated significant variance between taxa, with the integrated methodology enhancing the authentication process of various chicory taxa, suggesting that Egyptian chicory is part of a specific subspecies.

There is a well-known relationship between malignancy and impairment of kidney functions, either in the form of acute kidney injury or chronic kidney disease. In the former, however, bilateral malignant ureteral obstruction is a surgically correctable factor of this complex pathology. It warrants urgent drainage of the kidneys in emergency settings.

Tomatoes are an important agricultural product because they contain high concentrations of bioactive substances, such as folate, ascorbate, polyphenols, and carotenoids, as well as many other essential elements. As a result, tomatoes are thought to be extremely beneficial to human health. Chemical fertilizers and insecticides are routinely utilized to maximize tomato production.

Purpose: To identify the predictors of nadir serum creatinine (SCr) after drainage of bilaterally obstructed kidneys (BOKs) by different modes: double-J stent (JJ) versus percutaneous nephrostomy (PCN) and unilateral versus bilateral drainage.

Methods: A prospective non-randomized study was performed on patients with BOKs and raised SCr during December 2019-November 2021. Relevant variables were studied for improvement and non-improvement and for benign and malignant underlying obstructions (BUO and MUO).

The present study aimed to investigate the impact of salinity on vegetative growth, chemical constituents, and yields of cowpeas () and the possible benefits of salicylic acid (SA) on these plants after damage from salinity. To achieve these objectives, two pot experiments were carried out at the Faculty of Agriculture, Al-Azhar University, Egypt, during the two growing seasons of 2019 and 2020. The results revealed that salinity significantly decreased, and SA treatment substantially increased the plant height, number of compound leaves, number of internodes per plant, fresh weights of leaves and stems, productivity, photosynthetic pigments content, and concentrations of nitrogen (N), phosphorus (P), and potassium (K) of the cowpea plants compared with the control.

Serous ovarian carcinoma (SOC) is an ovarian cancer with a high fatality rate. Therefore, a lot of researchers have tried to identify novel prognostic biomarkers which might improve the patient prognosis. The aims of the study were to detect the tissue protein expression of Beclin-1 in addition to HIF-1α in SOC patients, to evaluate the relationship between their expression, the clinicopathological parameters, patients' prognosis, and the relation to chemotherapy resistance in SOC.
