Stabilization and improved properties of Salipaludibacillus agaradhaerens alkaline protease by immobilization onto double mesoporous core-shell nanospheres.

In this study, serine alkaline protease from halotolerant alkaliphilic Salipaludibacillus agaradhaerens strain AK-R was purified and immobilized onto double mesoporous core-shell silica (DMCSS) nanospheres. Covalent immobilization of AK-R protease onto activated DMCSS-NH nanospheres was more efficient than physical adsorption and was applied in further studies. DMCSS-NH nanospheres showed high loading capacity of 103.

Haptoglobin Phenotypes and Susceptibility to Parasites Infection in Central Sudan.

Haptoglobin (Hp) is an acute phase protein that binds the free hemoglobin (Hb), thus preventing iron loss and renal damage. Hp also has antioxidative and immunomodulatory properties. Three Hp phenotypes have been identified in human: Hp1-1, Hp2-1, and Hp2-2.

Assessment of Immunization to Hepatitis B Vaccine among Children under Five Years in Rural Areas of Taiz, Yemen.

. Hepatitis B virus (HBV) infection poses a major health problem worldwide. approximately 1 million deaths annually due to cirrhosis and hepatocellular carcinoma.

Plasmodium falciparum population structure in Sudan post artemisinin-based combination therapy.

Over the past decade, Sudan has stepped up malaria control backed by WHO, and this has resulted in significant reduction in parasite rate, malaria morbidity and mortality. The present study analyzed Plasmodium falciparum parasites in four geographical separated areas, to examine whether the success in malaria control following the use of artemisinin-based combination therapy (ACT) has disrupted the population structure and evolution of the parasite. We examined 319 P.

Genotyping of Pulmonary Isolates from Sudan Using Spoligotyping.

Tuberculosis (TB) remains a major public health problem worldwide due to its high risk of person-to-person transmission, morbidity and mortality [1]. Sudan has a high burden of tuberculosis. Spoligotyping (spacer oligonucleotide typing) a rapid method for genotyping of using the principle of reverse hybridization.

First report on Ambisome-associated allergic reaction in two Sudanese leishmaniasis patients.

Post kala-azar dermal leishmaniasis (PKDL) and mucosal leishmaniasis (ML) are serious clinical forms of leishmaniasis caused by Leishmania donovani parasites in Sudan. Although pentavalent antimonys are used as the first line of treatment of all clinical forms of leishmaniasis, persistent PKDL and ML patients are treated with liposomal amphotericin B (Ambisome) as a second-line drug. In this work, we report the development of allergic reactions by a PKDL and a ML Sudanese patient to Ambisome.

A case of Cornelia de Lange syndrome from Sudan.

Background: Brachmann de Lange syndrome (BDLS) is a multiple congenital anomaly syndrome characterized by a distinctive facial appearance, prenatal and postnatal growth deficiency, psychomotor delay, behavioral problems, and malformations of the upper extremities.

Case Presentation: Here we present for the first time a case of BDLS from Sudan, a 7-month-old female infant, who was referred as a case of malnutrition. The patient was from a Sudanese western tribe.

High frequency of Plasmodium falciparum PfCRT K76T and PfpghN86Y in patients clearing infection after chloroquine treatment in the Sudan.

The clinical response following treatment with chloroquine, and the prevalence of two Plasmodium falciparum DNA polymorphisms known to associate with drug resistance, namely PfCRT K76T and Pfpgh N86Y were investigated in two sites in central and eastern Sudan. Patient's sensitivity to chloroquine was determined according to the standard in vivo test as recommended by the WHO protocol in days 0, 3, 7 and 14, respectively. Clinical un-responsiveness was 75.
