 Electrophoretic patterns of serum protein in 12 Arabian race horses acutely infected with Babesia equi revealed a significant decrease in albumin (P<0.01) and beta globulins (P<0.05) where, alpha globulins fractions significantly (P<0.01) increased. No significant (P>0.05) changes were recorded in gamma globulins fractions and total serum protein.

AbstractThe pathophysiology of dry age-related macular degeneration (AMD) and specifically geographic atrophy (GA) has been linked to the complement cascade. This cascade is part of the innate immune system and is made up of the classical, alternative, and lectin pathways. The pathways comprise a system of plasma and membrane-associated serum proteins that are activated with identification of a nonself entity. A number of these proteins have been implicated in the development and progression of dry AMD. The three pathways converge at C3 and cascade down through C5, making both of these proteins viable targets for the treatment of dry AMD. In addition, there are a number of complement factors, CFB, CFD, CFH, and CFI, which are potential therapeutic targets as well. Several different complement-directed therapeutics are being studied for the treatment of dry AMD with the hope that one of these approaches will emerge as the first approved treatment for GA.

Heavy metals such as arsenic contribute to environmental pollution that can lead to systemic effects in various body organs. Some medicinal plants such as broccoli have been shown to reduce the harmful effects of these heavy metals. The main aim of the present study is to evaluate the effects of broccoli extract on liver and kidney toxicity, considering hematological and biochemical changes. The experimental study was performed in 28 days on 32 male Wistar rats classified into four groups: the control group (C), a group receiving 5 mg/kg oral arsenic (AS), a group receiving 300 mg/kg broccoli (B), and a group receiving arsenic and broccoli combination (AS + B). Finally, blood samples were taken to evaluate the hematological and biochemical parameters of the liver and kidney, as well as serum proteins’ concentration. Liver and kidney tissue were fixed and stained by H&E and used for histopathological diagnosis. The results demonstrated a significant decrease in white blood cells (WBC), red blood cells (RBC), and hemoglobin (Hb) in the AS group compared to other groups. However, in the B group, a significant increase in RBC and WBC was observed compared to the AS and C groups ( P  < 0.05). Moreover, RBC and WBC levels increased significantly in the AS + B group compared to the AS group ( P  = 0.046). However, in the AS group, aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, and creatinine levels increased, while total protein, albumin, and globulin decreased. This can be a result of liver and kidney damage, which was observed in the AS group. Furthermore, the increase in the concentration of albumin and globulin in the AS + B group was higher than that in the AS group. Infiltration of inflammatory cells and necrosis of the liver and kidney tissue in the pathological evaluation of the AS group were significantly higher than other groups. There was an increase in superoxide dismutases (SOD), glutathione peroxidase (GPx), and total antioxidant capacity (TAC); however, a decrease in malondialdehyde (MDA) concentration was seen in the AS + B group compared to the AS group. It seems that broccoli is highly effective at reducing liver and kidney damage and improving the hematological and biochemical factors in arsenic poisoning conditions.

Multiple myeloma (MM) is a clonal proliferation of plasma cells invading the bone marrow and secreting monoclonal immunoglobulin. In order to study the epidemiological and biological and biochemical characteristics of MM, we carried out a retrospective work on a cohort of 50 cases collected at the Avicenna Military Hospital in Marrakesh, during a period of 5 years (from January 2013 to December 2017). Our study included 32 men (64%) and 18 women (36%), with an average age of 60.6 years, with extremes at 44 and 87 years. The circumstances of discovery were dominated by bone pain and alteration in general condition, which are revealing in more than 65% of cases. Biologically: the sedimentation rate was accelerated in 86% of cases, a monoclonal peak appearance was revealed on serum proteins electrophoresis in 88%of cases, most often located in the γ zone (64%), a predominance of the Ig G isotype (64%), and kappa light chains in 60% of cases, Bence Jones protein (BJP) was found in 7 patients, i.e. 14% of cases, and plasmacytosis over 10% was found on the myelograms in 90 % of cases.

Acrylamide is a water-soluble compound that forms during the high-temperature cooking of starchy foods and has carcinogenic, neurotoxic, and genotoxic properties. Also, short-term exposure to acrylamide has been shown to cause significant hepatic injury in laboratory animals, along with disruption of antioxidant defense mechanisms due to excessive ROS production. Therefore, dietary antioxidants are believed to be useful in combating the negative effects of acrylamide. Corchorus olitoris L., also known as molokhia in Arabic, is a leafy vegetable which is shown to possess potent antioxidant and organoprotective properties. In this study, rats were administered with an aqueous extract of molokhia leaves to see if it could protect them against acrylamide-induced hepatic damage. Hepatic injury markers included serum total protein, total bilirubin, ALT, AST, and ALP, while oxidative stress markers included MDA, GSH, CAT, and SOD after dosing with three levels of extract (100, 250, and 500 mg/kg) for 21 days. Results indicated that the extracts substantially reduced elevated levels of bilirubin, ALT, AST, ALP, and MDA to normal levels at all doses. The extracts also brought serum protein, GSH, CAT, and SOD levels back to normal. Although the restoration of serum hepatic enzyme levels was dose dependent, no specific dose dependent relationship was found for serum proteins, MDA, GSH, CAT, or SOD activities. The study's findings show that molokhia leaves extract protects against acrylamide-induced hepatic damage by virtue of its good radical scavenging and anti-lipiperoxidative properties conferred by phenolics, flavonoids, and alkaloids.

Schistosomiasis is a chronic parasitic disease that continues to be a pressing public health problem in many developing countries. The primary pathological damage from the disease is granuloma and fibrosis caused by egg aggregation, and early treatment can effectively prevent the occurrence of liver fibrosis. Therefore, it is very important to identify biomarkers that can be used for early diagnosis of Schistosoma japonicum infection. In this study, a label-free proteomics method was performed to observe the alteration of proteins before infection, 1 and 6 weeks after infection, and 5 and 7 weeks after treatment. A total of 10 proteins derived from S. japonicum and 242 host-derived proteins were identified and quantified as significantly changed. Temporal analysis was carried out to further analyze potential biomarkers with coherent changes during infection and treatment. The results revealed biological process changes in serum proteins compared to infection and treatment groups, which implicated receptor-mediated endocytosis, inflammatory response, and acute-phase response such as mannan-binding lectin serine peptidase 1, immunoglobulin, and collagen. These findings offer guidance for the in-depth analysis of potential biomarkers of schistosomiasis, host protein, and early diagnosis of S. japonicum and its pathogenesis. Data are available via ProteomeXchange with identifier PXD029635.
