BACKGROUND: This study was done to know the distribution and frequencies of blood groups among blood donors attending voluntary blood donation camps organized by the Rajendra Institute of Medical Sciences (RIMS), Ranchi, Jharkhand so that demand and supply ratio of the four blood groups can be maintained so that no patient dies due to lack of a particular blood group. CONTEXT: Up till now about 400 red cells antigen have been identified. The majority follow Mendelian inheritance...

ABO blood group, except its direct clinical implications for transfusion and organ transplantation, is generally accepted as an effect factor for coronary heart disease, but the associations between ABO blood group and congenital heart disease (CHD) are not coherent by previous reports. In this study, we evaluated the the potential relationship between ABO blood group and CHD risk. In 39,042 consecutive inpatients (19,795 CHD VS 19,247 controls), we used multivariable logistic regression to evaluate the roles of ABO blood group, gender, and RH for CHD...

BACKGROUND: As adolescents rarely experience cardiovascular events, surrogate markers of atherosclerosis are useful to justify and monitor effects of primary prevention and therapy of risk factors. Endothelial function assessed by reactive hyperemic peripheral arterial tonometry (RH-PAT) resulting in a reactive hyperemic index (RHI) is a noninvasive method with limited data for use in children and adolescents.Methods and Results:We performed a total of 931 RHI measurements in 445 high-school students, aged 10-17 years, over a time period of 5 years...

Retinal haemorrhages (RH) and subdural haematomas (SDH) are frequently seen in abusive head trauma (AHT). The aim of our study is to show that they are suggestive, but not pathognomonic for AHT. We performed an observational retrospective study on children, aged 1-18 months old, admitted to the Antwerp University Hospital with RH. History, physical examination, medical course, coagulation and metabolic tests, skeletal survey, head circumference, retinal findings, cerebral imaging, and evaluation reports by social services or civil/criminal courts were collected...

INTRODUCTION: ABO blood groups are associated with some important chronic diseases. Previous studies have observed an association between ABO blood group and risk for obesity. OBJECTIVE: This study aimed to determine whether there is an association between ABO blood groups and obesity in apparently healthy attendees of primary healthcare (PHC) centers in Arar city, Northern Saudi Arabia. PARTICIPANTS AND METHODS: This cross-sectional study included 401 participants aged 15 years and older attending three randomly selected PHC centers in Arar city...

In the present study, we evaluated the effects of recombinant human (rh-)endostatin treatment on differentiated and undifferentiated tumor vasculature in Lewis lung cancer for the first time. Lewis lung carcinoma models were established. The animals were treated daily with varying doses of rh-endostatin or physiological saline for 14 days. Intravital microscopy was performed following treatment. The expression of CD31 and CD34 was determined by immunohistochemical staining, and microvessel density (MVD) was determined...

The aim of this study was to evaluate the effects of thermal manipulation (TM) during pre and post-hatch periods on thermotolerance of male broiler chickens exposed to chronic heat stress (CHS) during the finisher phase (34 ± 2°C, 6 h/day). Seven hundred fertile eggs of Ross 308 were assigned to the following groups: 1) control group incubated and housed in standard conditions, 2) pre-hatch treatment (PRE), the eggs were exposed to 39.5°C and 65% RH for 12 h, d from embryonic d 7 to 16 and after hatching the chicks where housed in standard conditions; 3 and 4) post-hatch TM at d 3 (PO3) and post-hatch TM at d 5 (PO5), which had the same incubation conditions as control and exposed to 36 to 38°C for 24 h at 3 and 5 days of age, respectively...

BACKGROUND: During Dec-2013, a chikungunya virus (CHIKV) outbreak was first detected in the French-West Indies. Subsequently, the virus dispersed to other Caribbean islands, continental America and many islands in the Pacific Ocean. Previous estimates of the attack rate were based on declaration of clinically suspected cases. METHODS/PRINCIPAL FINDINGS: Individual testing for CHIKV RNA of all (n = 16,386) blood donations between Feb-24th 2014 and Jan-31st 2015 identified 0·36% and 0·42% of positives in Guadeloupe and Martinique, respectively...

BACKGROUND: Toxoplasma gondii (T. gondii) is an obligate intracellular protozoan parasite with a broad host range including most warm-blooded animals, including humans. T. gondii surface antigen 1 (SAG1) is a well-characterized T. gondii antigen. T. gondii expresses five nonmitochondrial rhomboid intramembrane proteases, TgROM1-5. TgROM4 is uniformly distributed on the surface of T. gondii and involved in regulating MIC2, MIC3, MIC6, and AMA1 during T. gondii invasion of host cells. Bioinformatics have predicted ROM4 B-cell and T-cell epitopes...

Pectin has been widely used in a variety of biomedical applications. In this study, it was modified with sodium periodate as an oxidant and characterized by physicochemical methods Periodate oxidation increased the contents of dialdehyde units and carboxyl groups in pectin, and a decrease in pectin viscosity was measured. The oxidization reaction led to a significant decrease in all values of molecular weight and size (Mn, Mw, [η] and Rh) as determined by size exclusion chromatography (SEC), which allowed the selection of the oxidized pectin to be added to chitosan...

Red cell alloimmunization is a serious problem in chronically transfused patients. A number of high-throughput DNA assays have been developed to extend or replace traditional serologic antigen typing. DNA-based typing methods may be easily automated and multiplexed, and provide reliable information on a patient. Molecular genotyping promises to become cheaper, being not dependent on serologic immunoglobulin reagents. Patients with hemoglobinopathies could benefit from receiving extended genomic typing. This could limit post transfusional complications depending on subtle antigenic differences between donors and patients...

Osteoporosis is known as a degenerative disease of the skeletal system and its main complication is fracture, which influences quality of life in the elderly. There are 4 major blood groups in humans based on the presence of A and B antigens. According to the investigations, there are reported relations between blood types and some diseases. In this study, the association between the ABO blood group and the prevalence of osteoporosis and osteopenia in an elderly population was investigated. Medical records of 990 elderly people were investigated in a cross-sectional study and the association between their blood group and the incidence of osteoporosis and osteopenia was analyzed using SPSS version 17...

Since the establishment of People's Republic of China in 1949, the Chinese government has encountered several catastrophes related to transfusion transmitted diseases. The government's increasing attention to blood safety has prompted the initiation of a series of policies and measures that have enhanced the level of safety for the blood supply and met the basic clinical demands of blood for 1.3 billion people in the country. Blood donation screening strategies in China predominantly comprise donor screening and donor testing...

Non-specific antibodies or antibodies of undetermined significance (AUS) often pose problems for a blood bank technologist and physician. It is well known that antibodies can weaken and evanesce over time, thus eluding detection by routine blood bank techniques. Special enhancement techniques exist (eg, ficin treatment); however, they are often underutilized due to concerns over expense. Ficin is known to enhance reactivity caused by antibodies in the ABO, Rh, Kidd, Lewis, I, and P blood group systems, while destroying reactivity of antibodies in the Duffy, and MNS blood group systems...

BACKGROUND: Metastatic bone disease is a frequent complication of advanced non-small-cell lung cancer and causes skeletal-related events which result in a poor prognosis. A standard method to assess the therapeutic response of bone metastases does not currently exist. We used dynamic contrast-enhanced MRI to obtain quantitative measures to assess the suitability of this technique to gauge therapeutic response to vinorelbine-cisplatin plus rh-endostatinfor previously untreated non-small cell lung cancer with bone metastases...
