Hemoglobin variants, ABO and Rhesus blood groups are known to vary from one population to another. This study therefore sought the frequency of these indices among a cohort of pregnant women of African descent. The result will serve as a platform for instituting genetic counselling services with a view to reducing hemoglobinopathies and hemolytic diseases of newborns. One hundred and eighty two consenting pregnant women were recruited and screened for hemoglobin variants by standard alkaline cellulose acetate electrophoresis. ABO and Rhesus blood groups were determined by the hemagglutination technique. Of the 182 pregnant women screened, those with blood group O were the most prevalent (47.8%) followed by those with blood groups B (26.4%), A (19.2%) and AB (6.6%). Rhesus D antigen was positive for 86.3% and negative for 13.7% of the study population. This study reported the predominance of blood group O over the others. The prevalence of rhesus negative pregnant women was relatively very high (13.7%) compared to results from studies of unskewed populations in Nigeria. Also women with blood group B were found to be more being Rhesus negative than the others. Four types of hemoglobin genotypes were observed in this study. The most prevalent was HbAA (65.4%) followed by HbAS (32.4%) while HbSS and HbAC occurred with the same rate in the study population (1.1%). The relatively large number of rhesus negative pregnant women calls for close monitoring of pregnant women from this area because of the risk of developing moderate to severe forms of hemolytic disease of the new born. There was a low prevalence of sickle cells disease in this population (1.1%) although the prevalence of the sickle cell trait (32.4%) was above the earlier reported reference range for Nigeria. Therefore the culture of genetic counselling must be encouraged and sustained in the general population.

COMPARATIVE STUDY OF HEMOGLOBIN VARIANTS, ABO AND RHESUS BLOOD GROUPS AMONG LAGOS STATE RESIDENTSABO and Rhesus blood groups are known to vary from one population to another. They are the most clinically significant and prevalent blood group systems. Their relevance in blood transfusion science cannot be over emphasized. This study was designed for the purpose of updating information on the prevalence and distribution of ABO and Rh (D) blood groups among residents of Navy town, Ojo and its environs, Lagos State, Nigeria. ABO and Rhesus (D) phenotyping was carried out using standard tube techniques. Three thousand six hundred and four participants were recruited for this study. Gender distribution indicated that 2159 (59.9%) were females while 1445 (40.1%) were male. ABO blood group distribution indicated that 1868 (51.8%) were blood group O, 949 (26.3%) were blood group A, 657 (18.2%) group B and 130 (3.6%) were group AB. Of all the subjects tested, 3360 (93.3%) were Rh (D) positive while 244 (6.7%) were Rh (D) negative. The Rh D positive and Rh D negative distribution varied among the 4 ABO blood groups with O Rh D positive being the highest with 1786 (48.4%) while AB Rh D negative was the least with 6 (1.2%). The higher proportion of blood group O in this study is an advantage because blood group O blood that are negative for high titre anti A and B can potentially be transfused against ABO blood group barrier to group A, B and AB recipient. The low prevalence of Rh (D) negative blood group can also potentially reduce the incidence of Rhesus (D) -related haemolytic disease of the foetus and newborn in our environment particularly in the absence of universal access to prophylactic immunoglobulin D. Keywords: ABO, Rhesus (D) blood group, Lagos, Ikeja, Nigeria.

Abnormal hemoglobin variants, ABO, and Rhesus blood group distribution among students in the Niger Delta of Nigeria2010 •
This study was aimed to determine the frequency of ABO and Rh blood group patterns and hemoglobin threshold among pregnant women screened at Family Guidance Association of Ethiopia, North Area Mekelle model clinic. Checklists were prepared to collect data from laboratory registration books of five years to undergo this retrospective study. Those registration books were reviewed for ABO blood group, Rh profiles and hemoglobin threshold of the pregnant women screened during the specified period. A total of 5987 pregnant women have been found to be screened and the predominant phenotype in this study was O (41.5%) followed by phenotype A (28%), Phenotype B (25%) and phenotype AB (5.5%). Regarding Rh (D) system, 91.2% (5458/5987) women were positive for rhesus D antigen while the remaining 8.8% (529/5987) women were negative for the antigen. Blood grouping studies should be done in every region of the nation so that national transfusion policies can be drafted and supplying blood to the needy patients during emergency will be easier. Key words: ABO, Ethiopia, Rh, Tigray

Distribution of ABO, Rhesus Factor Blood Phenotype and Haemoglobin Genotype among Antenatal Clinic Attendees in Anyigba, North Central NigeriaBackground: In the practice of obstetrics and gynecology, the ABO and Rhesus factor (Rh) blood type are important. Blood typing for blood transfusion of compatible blood is very common in emergency and routine care. There is a scanty literature on the distribution of ABO and Rhesus blood types in Anyigba, (North central) Nigeria. Objective: This study aims to determine the distribution of ABO blood and Rhesus blood group phenotypes and Hemoglobin genotypes among antenatal clinic attendees in a teaching hospital. Methods: Antenatal records of attendees (October 2017 to September 2020) at the Kogi State University Teaching Hospital were retrieved and results of antenatal hematological investigations were collected using a structured tool.Bio data, ABO blood group, Rhesus group phenotype and Hemoglobin genotype were collected, inputted and analyzed using SPSS version 20. Results: The mean age was 26 +/- 7years, blood group O is most prevalent,561 (53.6%) then A 276 (26.4%), B 189 (18.1...

Haemoglobin genotype variants, ABO and Rh blood groups are known to vary from one population to another. Standard electrophoretic and haemagglutination techniques were employed in testing the blood samples. Of the 150 test subjects screened, HbAA in the male subjects were 58(48.0%) and 63(52.0%) in the female counterparts. The frequency of distribution of HbAA, HbAS, and HbSS in the subject were 121 (80.7%), 28 (18.7%) and 1 (0.6%). Also HbAS in the female was 16(57.1%) Original Research Article Richard et al.; JPRI, 33(29B): 149-157, 2021; Article no.JPRI.68773 150 while in male subjects was 12(42.9%). Blood group A (41.7%), group B(21.7%), group AB(28.6%) and group O(57.1%) were results for male subjects as against Group A(58.3%), Group B(78.3%), Group AB (71.4%) and Group O(42.9%) respectively in the female subjects.90% were Rh ‘D’ positive while 10% were Rh ‘D’ negative.

The halakhic category of li-fnim mi-shurat ha-din (often rendered as “beyond the letter of the law”) is frequently understood as referring to supererogatory behavior, which, of its very nature, is voluntary and not obligatory. Various halakhic authors, however, consider lifnim mi-shurat ha-din as obligatory (at least in some cases), and some even go as far as to maintain that it should be compulsory by court. Such a stance is surprising and paradoxical, for if one is expected, indeed demanded, to retract the law and to adopt a different norm in its stead, does not this imply a negative evaluation of the law? This paper seeks to consider such a possible conclusion. Its point of departure is Rabbi Shlomo ben Aderet’s (known by his acronym Rashba) interpretation of the Talmudic saying, that Jerusalem was destroyed (by the Romans) because rabbinic authorities of Second Temple times followed the laws of the Torah ל) א חרבה יר וש ל ים אל אעל ש ד נו בה ד ין ת ורה [TB Bava Metzia, 30b]), as suggesting that under certain circumstances one should not follow the Torah, and Rabbi Joshua Falk’s (16th century, Poland) similar view, in his Derisha u-Perisha commentary on the halakhic code of Rabbi Yaakov ben Asher, Arb‘a Turim. Following that view it discusses two Talmudic narratives, in which the halakhic norm is criticized by a rabbinic sage, claiming that one should adopt a higher moral standard, thus implying that the moral standard of the Halakha is at times problematic, and hence it is not always the appropriate path to follow.

إن هدف هذه المقالة – وهي غير موجهة إلى مجرمي الحرب ولا إلى ضحاياهم الذين تكفيهم همومهم – هو تمييز القضايا الأخلاقيّة التي أثارتها وتثيرها الحرب الإسرائيلية على الشعب الفلسطيني في قطاع غزة، ومعالجتها على حدة. والمقصود هو المعضلات الأخلاقية التي تواجه الإنسانية نتيجة للأعمال الوحشية التي تُرتكب خلال العدوان، والآليات (ميكانيزم) التي استخدمها لتحييد الحكم الأخلاقي على ما يُرتكب من جرائم.
