In this study the characteristics of raw and treated wastewater from Ninava drug factory were evaluated. The results revealed that the strength of raw wastewater can be classified as medium concentrated wastewater with respect to its BOD5 since the average value is 231.7 mg/l. In addition a strong correlations were found between many characteristics of raw waste. The characteristics of produced effluent from waste water treatment plant of the factory were within the Iraqi specification for the disposed wastewater constraints in 1997, where the average is 7.8 for pH, 40mg/l for SS, 2.8 mg/l for

Background and aims: Exercise training is a well-established therapeutic tool for treating type 2 diabetes. The purpose of this study is to examine the beneficial effects of personalized sprint interval training (SIT) and combined aerobic endurance and resistance training (Com) on insulin resistance and glycated hemoglobin A1c (HbA1c) concentration in women with type 2 diabetes. Methods: Fifty-two overweight female type 2 diabetic patients (age 45-60 years and body mass index [BMI] > 30) with HbA1c value of 6.5% or higher and fasting blood glucose (FBG) ≥ 126 mg/dL (7.0 mmol/L) were selected.

Background: Autologous platelet concentrate (APC)/platelet-rich fibrin (PRF) of second and third generations has increased use in periodontics to optimize wound healing. Few systematic reviews (SRs) have reported improved clinical outcomes, while other studies reported significantly better results for the connective tissue graft (CTG). There is still unclear clinical evidence about APC/PRF use to treat gingival recession (GR) defects. Then, the purpose of this SR was to evaluate the use of APC/PRF membranes (2nd and 3rd generations) in root coverage (RC) procedures and assess its efficacy as a

Abstract Background It has been postulated that genetic predisposition may influence the susceptibility to SARS-coronavirus infection and disease outcomes. A recent study has suggested that the deletion allele (D allele) of the angiotensin converting enzyme ( ACE ) gene is associated with hypoxemia in SARS patients. Moreover, the ACE D allele has been shown to be more prevalent in patients suffering from adult respiratory distress syndrome (ARDS) in a previous study. Thus, we have investigated the association between ACE insertion/deletion (I/D) polymorphism and the progression to ARDS or requ

Abstract Introduction In this single-center retrospective cohort study, we investigated the efficacy of letermovir in preventing Cytomegalovirus (CMV) infection in patients with aplastic anemia (AA) who have undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Based on whether or not letermovir was used for preventing CMV infection, the patients were categorized into two groups: letermovir and control groups. The overall survival (OS) rate and cumulative incidence of CMV infection during the first 100 days after allo-HSCT were evaluated. The study included 21 match

The standard treatment is an intralesional steroid injection with triamcinolone acetonide (TA). This method is effective, but there are some side effects include hypopigmentation and tissue atrophy. The nanofat method has been applied to various skin conditions with fewer side effects. Therefore, the use of nanofat with its regenerative properties can be expected to yield better results.
