ABSTRACT:

       Photovoltaic panels are used to generate electricity directly or indirectly. in the case of indirect, the energy should be saved in batteries and then it can be used and in this case, the inverter is required to change the direct current of the batteries(DC) to operate alternating current(AC) loads. This paper concentrates on saving energy in batteries and investigating the process of charging and discharging the batteries to operate selective loads in the paper. Using the photovoltaic panels to store energy in batteries, the results reveal that one photovoltaic panel of( 80 W) is placed towards south at a tilt angle of 36o; it could generate (224 W.hr) of energy that was obtained by charging a( 65 A.hr) lead-acid battery for 13 hours in April. Using two solar panels each of( 80 W )is connecting parallel,( 915.6 W.hr) of energy generated in May while using three units in parallel connection the electricity generated was near to that of two panels as the battery reaches nearly the full charge. Ambient temperature rise harms solar panels and leads to a decrease in the efficiency of the solar panel.

ABSTRACT:

Postcoital bleeding is a worrying, for both women and health care provider. This study aimed to evaluate the prevalence of abnormal cervical cytology among patient with PCB in the private outpatient care setting, and to identify risk-factors for cervical pathology among these patients. A cross sectional study of 90 patients presented to the privet clinic, during the period 1st feb-1st Des. 2019. Inclusion criteria include married women presented with post coital bleeding, non-pregnant, all patients undergo Pap Smear Cytology.

The commonest age presented with PCB was 40-44 years old 22(24.4%), followed by (45-49) years and (25-29) years 18(20%). Those aged ≥40 years 44(48.9%), and those aged ≤34 34(37.8%). The mean parity was 4.7±2.8, hormonal contraception was commonly used by those with PCB followed by intra uterine contraceptive device (IUCD), 30(33.3%), 18(20) respectively. Most of the patient were House wives 78(86.7%), The physical examination show that most patient had cervical erosion 68(75.5%), followed by healthy cervix in 12(13.3%), while suspicious features was found among 6(6.7%), Moderate and sever dysplasia was found more among those aged ≥40 years 10(22.7%), while it was 4(8.7%) among those aged < 40 years.

there is higher prevalence of High-grade squamous intraepithelial lesions among females with PCB, and non- significant difference among those aged less or more than 40 years. Therefore it’s important to examine any patient complaining of PCB with PAP smear cytology and colposcopy examination.

ABSTRACT:

Pregnant women are a risk group vitamin D insufficiency found among greater than 50% of pregnant females. Actually, there few researches and knowledge which associate the Maternal 25(OH) D level and premature labour, and no one carried in Iraq. The aim of this research is to find out any relation between the maternal plasma 25(OH) D levels of females who have gave birth to premature (< 36 weeks) in comparison to females with full-term neonates in both groups.  The current study is a case control research was carried out between January-August 2020, at the department of gynecology and obstetrics at Azadi Teaching Hospital in Kirkuk Governorate. A convenient sample was randomly selected consist of 30 Mothers with premature delivery, compared with 30 mothers term pregnancy delivery, the newborns were weighing >2500g and appropriate for gestational age. Revision of maternal ANC cards were carried out for investigations, ultrasonography, date of LMP of mothers’, as well as fetal anthropocentric measurements through the conception period. The mean Vitamin D level was (18.6±6.7) among preterm deliveries, which is lower significantly from those with full term delivery (27.5±6.2), P value < 0.0001, as represented in figure 1. Deficient vitamin D level was reported among 15(50%) of preterm delivered mothers versus 6(20%) of full term mothers. insufficient vitamin D level was reported among 12(40%) of preterm delivered mothers versus 9(30%) of full term mothers. sufficient vitamin D level was reported among 3(10%) of preterm delivered mothers versus 15(50%) of full term mothers. The low levels Vitamin D level is significantly associated with premature deliveries.

Abstract:

Poly methyl methacrylate (PMMA) is one of the most widely used materials in modern prosthodontics. It is widely known due to its simplicity in use and acceptable aesthetic. A new concept of polymerization fluid resin technique was instead of heat and gypsum material. Forty specimens were prepared from two brands of fluid acrylic resin. The samples were divided into two groups, the first one was the control while the other group was incorporated with silver nanoparticles(modified). The tests performed were impact strength, transverse strength, color stability and candida retention ability on the samples. 10 samples for each test were used.  The results showed that modified group had significantly higher impact strength than the control group. There was non-significant difference between group of modified fluid acrylic and control group. Regarding color stability, there were highly significant color change after 10 days of immersion in the tea solution for the modified group the results of the biological test showed that the candida retention of the control group was significantly higher than modified group.

Within the limitation of this study it can be concluded that addition of silver nanoparticles has resulted in significant difference between control and modified group for impact strength test. While non-significant difference was seen for transverse strength test. In regard to color stability, showed enhancement in color stability for both before and after placement in tea solution. Addition of silver nanoparticles also caused reduction in candida albicans retention in the added samples.

Keywords: PMMA, fluid resin, Impact strength, Candida albicans.

 ABSTRACT:

In medicine, blood groups play an active role. A noticeable relationship is observed linking ABO with the Wilbrand factor and vWF deficiency which results in hemorrhagic disorders, while increased levels are a risk factor for blood clotting. Previous investigations found that individuals in group O have long hemorrhageand blood clotting time. The aim of the current study is to evaluate the bleeding time relationship with the different blood groups and sex also. This cross-sectional study includes 95 students aged between 18 and 20 years. Permission has been takenfrom the students participated in this study before the bleeding time (the method of filter paper for Duke) was determined.The obtained results showed a longer time of bleeding among the AB group. Moreover, the bleeding time is longer in women than men. For more results, it is necessary to involve a larger research group.

Keywords: Bleeding time,  Blood groups, Factor of von Wilbrand.

ABSTRACT:

This study assessed the protective effect of Zizphus jujube (ZJ) extract on 5‑FU‑induced alterations in renal function markers and kidney morphology in Dawley rats. Twenty-four rats were divided randomly into four groups administrated orally with 0.9% normal saline as the control group, 5-FU (40 mg/kg daily for 5 days), ZJ (500 mg/ kg daily for 5 days), and 5-FU‏+ ZJ (for 6 days). further biochemical experiments carried out on blood collected from the heart. Kidney tissues were obtained for analysis of catalase (Cat), glutathione S-transfers (GST), and lipid peroxide levels as well as histology analysis. 5-FU significantly reduced the enzyme activity of Cat and GST and increased levels of lipid peroxidation and plasma creatinine levels (P < 0.005). Histopathological examination showed severe wide ischemia of proximal convoluted tubule (PCT), missing in Bowman’s space, and edema in the group treated with 5-FU. In addition, pretreatment with ZJ has significantly improved levels of Cat and GST and reduced lipid peroxidation and plasma creatinine levels (P < 0.05). Moreover, the histopathological analysis showed that ZJ relatively prevented the damage in renal tubular cells compared with 5-FU treated group. Supplementation with ZJ may have clinical benefit in nephrotoxicity caused by 5‑FU.

Keywords: antioxidant; 5-Flurouracil, ziziphus jujube, nephrotoxicity, glutathione S-transferase, catalase, histological analysis.

ABSTRACT:

Polycystic ovary syndrome is a common cause of an ovulatory infertility. Drugs like Aromatase inhibitors, Human menopausal gonadotropin, used for ovulation induction. The aim of this study was carried out to compare the therapeutic effects of gonadotropin hormone versus oral ovarian stimulating agents. A prospective randomized controlled clinical trial was carried out in the Salahdeen general hospital in Tikrit from 1st Feb-30th August 2020. About 75 PCOs patients enrolled randomly in the study and divided equally into 3 groups as below:  Group A treated with (75 IU intramuscular HMG gonadotropin) daily for 5 days starting Day 2 of menstrual cycle. Group B treated with oral clomiphene citrate 100 mg daily for 5 days starting Day 2 of menstrual cycle. Group C treated with oral Letrezole 5 mg daily for 5 days starting Day 2 of menstrual cycle. Multiple mature follicles were obtained commonly by HMG, followed by Letrozole, then Clomiphene, this relation was statistically significant.  Endometrial thickness was higher among those treated with HMG (10.5±1.7) than those treated by Clomiphene (9.03±0.9), and then treated by letrozole (8.5±1.2). This is a significant difference in ET value between Clomiphene, letrozole, and HMG. Chemical pregnancy (early pregnancy loss that occurs shortly after implantation may account to 50-75% of all miscarriages) was higher among those treated with HMG (20%), while it was (16%) of those treated with Clomiphene, and (12%) of the Letrozole group, this relation was statistically not significant. In conclusion, HMG had the highest response rate, followed by Letrozole, and Clomiphene. The multiple mature follicles were obtained commonly by HMG, followed by Letrozole, then Clomiphene.

Keywords: Human Menopausal Gonadotropin Hormone, Polycystic Ovary Syndrome, Ovulation induction.

Abstract:

Preterm labor is known as delivery prior to 37 completed weeks of gestation. Because 10% of total labors are preterm and 70% of neonatal mortality is caused by this problem, preterm labor is a significant problem in obstetrics, pediatrics & midwifery. This study aims at comparing the efficacy as well as adverse effects profile of (human chorionic gonadotropin hormone and magnesium sulphate) in suppression of preterm labor.

This study was designed as a prospective comparative randomized clinical trial done from 4th April to 1st September 2020. The study population included pregnant women with preterm labor, who were admitted to Salah Al Din General Hospital, in Tikrit city. Sixty two cases who consented (Informed written consent was obtained from all the patients) were randomly allocated to 2 different intervention groups, named A and B. Group A and B consisted of 30 and 32 pregnant women, respectively. All cases were admitted in labour room and baseline investigations were done. Group A: For patients of group A: received an intravenously loading dose of 4 g (1 g/min) Magnesium sulphate. A continual infusion of 2 g per 1 hr was then administrated. The infusion was continued until 12 h of uterine quiescence is done. Group B: (32 women), intramuscular injection Human Chorionic Gonadotropin was administered as an initial dose of 5000 IU. Half hourly assessment of uterine contractions, maternal vital signs, fetal heart rate monitoring was done. All of the patients were under monitoring in the hospital until 24 h of the end of drug infusion. Also, both of the groups received Betamethasone, 12 mg every 24 hr for 2 doses. Patients were under control until the end of pregnancy.

It was foun that Delay of Labour for ≥21 day was higher among Human Chorionic Gonadotropin group (68.8%) than among MgSO4 group (60%), and delivery within <2 days was higher among HCG group (9.4%) than among MgSO4 group (6.7%). The mean duration in hours from time of start of treatment with Magnesium sulphate to the contraction suppression was (2.9±0.08) lower than of the HCG treatment group (3.11±0.13). The commonest side effect of MgSO4 was thirst (50%), hyperthermia (46.67), and head ache (30%), dizziness (30%), while there is no side effect among HCG group except single case complained of head ache (3.13%),

It was concluded that magnesium sulphate is better than Human Chorionic Gonadotropin in stopping preterm labour with faster onset of action than Human Chorionic Gonadotropin but had side effects for mothers more than Human Chorionic Gonadotropin.
