EXTRACTION AND CHARACTERIZATION OF RICE BRAN OIL (RBO) FOR POTENTIAL APPLICATION AS BIODIESEL
No full textAbstract: Rice bran oil (RBO) is a potential feedstock for biodiesel and biolubricant production among other alternative sources. The rice bran’s fat extraction was carried out using maceration with chloroform, solvent recovery as a means of purification was carried out using rotary evaporator. Physicochemical analysis such as percent extraction and Gas Chromatography-Mass Spectrometry (GC-MS), iodine value, peroxide value and saponification values were carried out to ascertain its potential application as Biodiesel. From the GC-MS analysis, over 30 compounds including fatty acids and other phytochemicals were discovered with Oleic acid having the greater percentage of 34.5% having the base peak at m/z of 282.
Keywords: Rice bran oil (RBO), biodiesel, biolubricant production.

Growth performance of juveniles Oreochromis niloticus reared with two different diets in Kunduchi Ponds, Dar Es Salaam, Tanzania
No full textComparative study was conducted to observe the growth performance, length-weight relationship and condition factor of Oreochromis niloticus fed with two different diets using standard methods and procedures. The fish were fed with two different formulated diets Agric- Aqua Feed (AAF) and Kunduchi Locally processed Feed (KLF) for a period of six weeks. Maximum weight gain of (10.74 to 12.48 g) was recorded with Kunduchi locally feed (KLF) with specific growth rate of (5.56 to 6.37 % per day), while minimum weight gain of (8.42 to 9.54 g) was recorded with Agric Aqua Feed (AAF) with specific growth rate of (5.14 to 5.73 % per day). No feed-related mortality was observed during the whole experimental period. There were no significant differences (p=0.4618) in the ‘b’ values among all the experimental ponds and the value of the exponent ‘b’ ranged from (2.38 to 4.03) indicating both negative and positive allometric growths. The condition factor ‘K’ of all the experimental fish was above 1.0 (1.53- 1.89) indicating robustness or well being of the fishes from all the experimental ponds. The use of locally processed formulated diet such as KLF is therefore recommended as a step in boosting the aquaculture sector.Keywords: Condition factor, formulated diets, growth performance, Length- weight, Oreochromis niloticu
Clinical characteristics and outcomes of Yemeni patients with acute heart failure aged 50 years or younger. data from gulf acute heart failure registry (gulf CARE)
No full textAims: There is a shortage of data about acute heart failure (AHF) in the young, including its underlying causes, clinical presentation and outcomes. We aim to describe clinical characteristics, causes and outcomes of AHF in
Yemeni patients aged 50 years or younger. Methods and results: we evaluated Yemeni patients with AHF enrolled in Gulf CARE registry. Patients were divided into two groups: young patients (≤50 years) and older patients N50 years). A total of 1536 patientswith AHF were enrolled, of whom635 (41.3%)were 50 years old or younger. Themean age for this groupwas 38.8 (±9.5) years; and 399 (62.8%) were males. Younger patients had a higher prevalence of non-ischemic cardiomyopathy (41% vs 11.1%, p b 0.001), primary valvular disease (27.9% vs 3.2%, p b 0.001), viral myocarditis (0.8% vs 0, p b 0.001). Ischemic heart disease (61.6% vs 25.5%, p b 0.001) and hypertensive heart disease (18.3% vs 6.3%, p b 0.001) were more frequent in the elderly group. Cardiogenic shock was more frequent among younger patients (13.7% vs 7.0, p b 0.001). In-hospital mortality was higher in patient aged ≤50 years (12% vs 7.6%, p = 0.002) while no difference in all-cause mortality was present at 3 months (17.8 vs 14.5, p = 0.089) and after 1 year (21.9% vs 20.6%, p = 0.56). Conclusion: This analysis of Gulf CARE registry represents the largest report of patients admitted with AHF in Yemen. There were differences among cause of HF and precipitating factors of AHF among younger and elderly patients. Younger patients had higher in-hospital mortality and more severe clinical condition at admissionAims: There is a shortage of data about acute heart failure (AHF) in the young, including its underlying causes, clinical presentation and outcomes.

The Role of Using Motorized Diamond Burr Polisher Instrument in Minimizing the Recurrent Rate of Pterygium Excision
No full textTo compare the effects of using motorized diamond burr polisher in pterygium excision versus manual polishing of the corneoscleral bed in reducing the recurrent rate. A prospective, comparative and interventional study of 90 consecutive patients with different grads of primary pterygium, who underwent pterygium excision at Shahid Aso teaching eye hospital in Sulaimani city, between August 2018 till September 2019, which was performed by single surgeon. In group A (45) eyes polishing of the corneoscleral bed done using motorized diamond polishing burr, and in group B (45) eyes using manual crescent blade for polishing. Recurrent rate was evaluated after about (8±2) months postoperatively. Ethical consideration of the risks and the benefits of the procedure was observed for each individual patient. A 90 patients with the mean age of group A (48.84±12.7) years and group B (49.67±12.3) years, complained of different grads of primary pterygium, group A had 31(68.9%) male and 14(31.1%) female, while group B had 22(48.9%) male and 23(51.1%) female. Each individual factors like age, gender, visual acuity, BCVA pre and postoperatively, IOP measurement, dryness of the eye and risk factors like smoking and UV exposure affecting the recurrence were assessed. In both groups the main indication for surgery was sign of irritation. The mean surgical time was calculated and the difference between two groups were significant. After follow-up of average six months the outcomes and recurrent rate were checked, recurrent rate was in group A 1(2.2%) while in group B was 6(13.3%) patients. it significantly decreased. Corneal scar happens in only 1(2.2%) case of group A while in 11(24.4%) cases in group B, Corneal scar was statistically significant. In both groups the change of BCVA was significant but the visual change was more significant in group A in compare to group B. Motorized diamond burr is a safe instrument for polishing the cornea during pterygium excision, it is easy to handle, low price, need lesser operative time, its effect on recurrence postoperatively is significant and beside it leaves lesser corneal scar and early visual recovery postoperatively.  
Cephradine Bioequivalence and its Interaction with Khat and Food (Al-Sayadeyah) in Yemen
No full textThe pharmacokinetic parameters and bioequivalence of three oral
brands of cephradine capsules were estimated and compared to that of
reference standard product. The study was carried out in eight healthy,
adult, male Yemeni volunteers after fully understood the purpose of the
study and give their approval in a written consent form.
Four – way crossover trials were performed using a single dose
(500 mg) of cephradine on an empty stomach preceded by an overnight
fast. Urine samples were collected at specified time intervals following
the drug administration. Volunteers were allowed to take only water to
enhance dieresis until 2 hours after medication. Standard breakfast was
then served. A 7 days washout period was allowed between trials. The
urine samples were kept at 4 C
0
only one day till analysis.
Samples were analyzed by HPLC system. The pharmacokinetic
parameters (Mean ± SD) of the percentage dose excreted unchanged in
urine over 12 hrs (PDE%) and the maximum peak of the urinary
excretion rate (MPE, mg/min) togetherwith the time taken to reach this
peak (TTP, hrs) were used to describe the extent and rate of
bioavailability respectively.
The extent of cephradine bioavailability, expressed as PDE%, for
brands A, B, C, and D was in the order D > A > B > C (75.3 ± 13.9, 74.2
± 10.6, 72.8 ± 17.4 and 69.8 ± 13.6, respectively).
The rate of cephradine bioavailability, expressed as MPE, for the
four brands was in the order D > A > B > C (4.3 ± 0.8, 4.1 ± 1.37, 3.98 ±
0.86 and 3.7 ± 1.4, respectively).
The values of TTP for the four brands (C > A = B = D)
were found to be highly comparable(1.3 ± 0.56, 0.84 ± 0.25, 0.84
± 0.25and 0.84 ± 0.25, respectively).
The half lives for brand A, B,C and D are 0.71, 0.94, 0.98
and 0.84, respectively and the elimination rate constants for brand
A, B, C and D were 0.98, 0.73,0.71 and 0.83, respectively.
The relative bioavailability of each of the three brands B,
C and D compared to the reference brand A is in the range 80 -
120 %.
Statistical analysis using student’s t-test showed that there
are no statistically significant differences in all pharmacokinetic
parameters between the three brands B, C and D and the reference
standard product A (Pֿ> 0.05). However, TTP of brand C was
found to be significantly different compared to brand A (Pֿ<
0.05).
Studies on the effect of Khat and common Yemeni food (AlSayadeyah) on the bioavailability of reference brand A were performed in
the same way as the bioequivalence studies, except that the drug was
administered with khat in the first trial and with food in the second one.
The results of these studies are summarized in the following table:
Parameter Brand A
Fasting
Brand A
with Khat
Brand A
with Al-Sayadeyah
PDE (%) 74.2 ± 10.651.6±1055.3±19.8
MPE, (mg/min) 4.1 ± 1.372.6± 0.6 1.9 ± 0.8
TTP (h) 0.84 ± 0.252.2 ±0.73.1 ± 0.9
t½(hr) 0.71 0.5 0.72
Ke(hr
-1
) 0.98 1.4 0.96
Statistical analysis using student’st-test showed that there are
statistically significant differences in all pharmacokinetic
parameters when Brand A is given in fasting condition and with
either Khat or Al-Sayadeyah (P < 0.05).
Khat and Al-Sayadeyah effectin the bioavailability of
cephradine and decrease absorption of cephradine 50 %.
The study concluded that the four brands A, B, C and D are
bioequivalent and they can be used interchangeable.
Bioequivalence studies were recommended to be performed for all
oral dosage forms locally marketed and manufactured before
issuing their certificate of registration.
The study recommended the avoidance of chewing Khat
and eating Al-Sayadeyah for atleast three hours following
cephradine and similar drugs administration
