Co-administration of resveratrol rescued lead-induced toxicity in Drosophila melanogaster.

Lead toxicity poses a significant environmental concern linked to diverse health issues. This study explores the potential mitigating effects of resveratrol on lead-induced toxicity in Drosophila melanogaster. Adult fruit flies, aged three days, were orally exposed to lead (60 mg/L), Succimer (10 mg), and varying concentrations of resveratrol (50, 100, and 150 mg). The investigation encompassed the assessment of selected biological parameters, biochemical markers, oxidative stress indicators, and antioxidant enzymes. Resveratrol exhibited a dose-dependent enhancement of egg-laying, eclosion rate, filial generation output, locomotor activity, and life span in D. melanogaster, significantly to 150 mg of diet. Most of the investigated biochemical parameters were significantly rescued in lead-exposed fruit flies when co-treated with resveratrol (p < 0.05). However, oxidative stress remained unaffected by resveratrol. The findings suggest that resveratrol effectively protects against lead toxicity in Drosophila melanogaster and may hold therapeutic potential as an agent for managing lead poisoning in humans.

Prevalence and risk estimates of Cryptosporidium oocysts infection associated with consumption of raw-eaten vegetables in Maiduguri metropolis LGAs, Northeast Nigeria.

Cryptosporidium is one of the most important protozoan parasitic pathogens, and it is a common cause of diarrhoea in humans, domestic animals, and wild vertebrates and has serious public health threats. A cross-sectional study was designed to determine the prevalence of Cryptosporidium oocysts in raw-eaten vegetables in Maiduguri Metropolitan Council (MMC) and Jere Local Government Areas (LGAs). A total of 400 samples were collected from four (4) different locations, namely Tashan Bama, Gomboru, and Monday Markets (n = 100), while fifty (n = 50) each from 202-Vegetable-Vendors and Unimaid Commercials. A total of 16 visits were conducted in all the sampling areas (twenty-five samples per visit). The Cryptosporidium oocysts were detected using the Modified Ziehl-Neelsen Staining Technique. The locations, sources, and types of raw-eaten vegetables were also assessed. The oocysts were confirmed (100×) as bright pink spherules. Data generated were analyzed using IBM-SPSS V23.0, and p ≤ 0.05 was considered significant. Out of the total samples (n = 400) analyzed, cabbage appeared to have the highest number of 10 (12.5%) of Cryptosporidium oocysts detected, while Tomato and garden egg had 9 (11.3%) and 1 (1.2%), respectively. There was a statistically significant association (χ2 = 12.5, P = 0.014) between the presence of Cryptosporidium oocysts in raw-eaten vegetables and vegetable types. Among the sources of the vegetables sampled, Alau had the highest number of Cryptosporidium oocysts, 15 (12.5%), followed by Kilari-Abdullahi and Zabarmari sources with 4 (10.0%) and 4 (5.0%), respectively. However, Jetete appeared to have the least number 2 (2.5%) of oocysts, and there was a statistically significant association (χ2= 10.4, P = 0.034) between the presence of Cryptosporidium oocysts and the sources of vegetables and fruits. The study concludes that the raw-eaten vegetables sampled from Maiduguri Metropolis were contaminated with Cryptosporidium oocysts. The study recommends that all raw-eaten vegetables should be from cleaned sources and washed before consumption. Consumers should be enlightened on the hygienic measures in the food chain in line with the Hazard Analysis and Critical Control Points (HACCP) principles.

Sonographic evaluation of maternal uterine artery from 11 - 30 weeks 6 days of gestational age in a Nigerian population: A predictive index for pre-eclampsia and intrauterine growth restriction.

INTRODUCTION: Uterine artery (UtA) Doppler sonography is a potential screening tool for pregnancy complications in placental insufficiency. Evaluation of the maternal and fetal vessels in pregnancy ensures accurate identification and prediction of pregnancy complications, such as preeclampsia (PE) and intrauterine growth restrictions (IUGR). The study aims to establish local reference values for UtA in a Nigerian population. METHODS: This prospective longitudinal study was conducted among 230 pregnant women. All participants had their left (Lt) and right (RT) UtAs evaluated with a Doppler ultrasound from 11 to 30 weeks 6 days of gestational age. Peak systolic velocity (PSV), End diastolic Velocity (EDV), Systolic/Diastolic ratio (S/D), Pulsatility Index (PI), and Resistivity Index (RI) were measured and documented. RESULTS: The mean values of UtA at 11-30 weeks 6 days of GA ranged as follows: 0.79-0.53 (RI), 1.83-0.79 (PI), 5.16-2.23 (S/D), 96.37-98.00 (PSV) & 26.07-44.14 (EDV). While the mean values of the Rt. & Lt. UtA 's ranged as follows: 0.79-0.50 (RI. Rt), 0.78-0.56 (RI. Lt), 2.05-0.80 (PI. Rt), 1.61-0.78 (PI. Lt), 6.03-2.13 (S/D. Rt), 4.29-2.33 (S/D. Lt), 89.79-99.23 (PSV. Rt), 102.76-96.71 (PSV. Lt) & 23.31-45.25 (EDV. Rt), 28.83-43.02 (EDV. Lt) respectively. CONCLUSION: UtA Doppler reference range was established in the study population. These reference ranges will be of clinical value in daily obstetric practice. IMPLICATION FOR PRACTICE: Obstetricians and sonographers will apply these values for early prediction of pregnancies at risk of complications in the locality.

A new cyclic polyketide and other constituents from Ononis spinosa growing wildly in Jordan and their antioxidant activity.

The new cyclic polyketide 7,9,11-trihydroxytetracos-2-eneoic acid δ-lactone (1), together with other eleven known compounds, were isolated from Ononis spinosa, growing wildly in Jordan. All isolated compounds were identified by thorough investigation of their spectral data including NMR and HRESIMS. Antioxidant activity testing of puerol B, specionin and the new cyclic polyketide revealed that puerol B had the highest DPPH radical scavenging activity (IC50 0.09 ± 0.006 mg/ml) as compared to α-tocopherol (IC50 0.039 ± 0.0006 mg/ml), while specionin had the highest ABTS radical scavenging power (IC50 0.013 ± 0.0008 mg/ml) as compared to α-tocopherol and ascorbic acid (IC50 0.042 ± 0.0004; 0.026 ± 0 .0007 mg/ml; respectively).

Esophageal cancer epidemiology, diagnosis, and management in Sudan - A review.

INTRODUCTION: In Sudan, cancer a common health challenge, is the leading cause of death after malaria and viral pneumonia. The aim of the review is to determine the risk factors associated with esophageal cancer (EC) among Sudanese population. METHODS: All published online data concerning EC epidemiology, diagnosis, and management in Sudan were studied. RESULTS: The prevalence of EC in Sudan is ranked fourth among cancer types in males and fifth in females. The squamous cell carcinoma is more predominant than adenocarcinoma. The dietary, dysplasia and teeth loss, cigarette smoking, age, sex, GERD, genetic and environmental interactions remain a risk for developing EC in clinical practice. A significant challenge for treatment is that most of EC patients were often diagnosed in advanced stages due to the lack of early clinical symptoms. Management of EC depends on patient fitness and tumor stage, endoscopic removal was used for early tumors, while chemotherapy, chemo-radiotherapy, surgical resection, or combinations of these were used for advanced tumors. Despite improvements in the management and treatment of EC patients, the general outcome remains very poor. Furthermore, using molecular techniques to better understand the etiology of EC, it may assist in identifying complicated and critical issues and improve therapy towards a new treatment strategy. CONCLUSION: The remarkable factors associated with EC among Sudanese are geographical variation, environmental factors, ethnic differences, dietary and social habits.

Aroma Profiles Analysis of Two Populations of Salvia palaestina Benth. Collected from Mediterranean and Irano-Turanian Zones in Jordan.

The volatile principles emitted from different aerial organs of two S. palaestina Benth. populations (Mediterranean (Med) and Irano-Turanian (IrT)) growing wild in Jordan were extracted by Solid Phase Micro-Extraction (SPME) and analysed by GC/MS technique. Sesquiterpene hydrocarbons dominated stems (59.38%, 49.67%) and leaves (93.28%, 32.39%) emissions from Med and IrT zones, respectively while monoterpene hydrocarbons had the major contribution to the aroma of pre-flowering buds (78.62%, 74.96%), opened flowers (76.12%, 59.99%) and petals (69.57%, 54.28%) and were mostly represented by sabinene (in Med zone) and ociemene isomers (Z & E) in IrT zone. Multivariate analysis classified the two populations into two different clusters based on their origin and indicated the occurrence of two ecotypes of this species. Different organs from the same collection site showed emission profiles of similar chemical composition.

Ethnomedicinal documentation and anti-inflammatory effects of n-butanol extract and of four compounds isolated from the stems of Pituranthos scoparius: An in vitro and in vivo investigation.

ETHNOPHARMACOLOGICAL RELEVANCE: Pituranthos scoparius is a medicinal plant belonging to the Apiaceae family. It thrives in North Africa, and is widely distributed in the high plateau of most parts of the Sahara in Algeria. This plant is widely used in the Algerian traditional medicine to treat numerous infectious diseases, dermatoses, nervous breakdowns, digestive disorders, and calm abdominal pain. AIM OF THE STUDY: The aim of the present work was to examine the ethnomedicinal uses of Pituranthos scoparius in Setif region, Algeria, isolate and identify the chemical constituents of the n-butanol stem extract of P. scoparius (BEPS), and to determine the toxicity and anti-inflammatory effects of these compounds in addition to the extract. MATERIALS AND METHODS: The anti-inflammatory effects of BEPS and the four compounds isolated from the extract were evaluated using the in vitro protein denaturation assay, whereas the topical anti-inflammatory activity was assessed using the croton oil-induced ear edema in mice. Toxicity was determined based on assessment of in vitro cytotoxicity using hemolytic activity against human red blood cells (RBCs). RESULTS: Four compounds, identified as the rare isorhamnetin-3-O-ß-apiofuranosyl (1 â†’ 2)-ß glucopyranoside (2), in addition to three known compounds, namely isorhamnetin-3-O-ß-glucoside (1), D-mannitol (3), and isorhamnetin-3-O-ß-glucopyranosyl-(1 â†’ 6)-ß-glucopyranoside (4) were isolated from BEPS. These compounds were characterized by means of NMR and high-resolution mass spectral (HRMS) data. These four compounds were isolated for the first time from this traditional Algerian medicinal plant. Screening of the extract indicated the presence of alkaloids, polyphenols, flavonoids, free quinones, coumarins and tannins. Topical anti-inflammatory effect showed that the four isolated compounds, as well as BEPS, exhibit a significant (p < 0.05) dose-dependent (0.5 and 1 mg/ear) anti-inflammatory effect. At a dose of 1 mg/ear, compounds 1, 2, and 4, exhibited remarkable anti-inflammatory effect with a percentage inhibition of 85.50 ± 2.78, 79.78 ± 4.68, and 75.78 ± 2.98%, respectively. Results from in vitro cytotoxicity showed that the % lysis of the extract, along with isolated compounds was found to be virtually nontoxic. CONCLUSIONS: These results suggest that BEPS and isolated compounds are safe, nontoxic, and exert remarkable anti-inflammatory effects, and can be new sources of natural anti-inflammatory agents.

Synthesis of composite sorbent for the treatment of aqueous solutions contaminated with methylene blue dye.

To apply the principles of sustainability, this study aims to prepare the composite sorbent from mixing of solid wastes that resulted from activities of treatment plants for wastewater and water supply. The manufacturing process depends on the mixing of sewage sludge with waterworks sludge at different proportions and the best mixture is modified by ferric nitrate solution. The prepared composite sorbent was evaluated as permeable reactive barrier (PRB) in the capturing of methylene blue (MB) dye presented in the simulated groundwater. Results proved that the suitable mixture of composite sorbent consisting of 0.25 g sewage sludge with 0.75 g waterworks sludge coated with aqueous solution of 2 g of Fe(NO3)2 achieved the maximum sorption capacity. In comparison with Freundlich model, Langmuir expression described the sorption measurements in a well manner; so, the chemisorption is governed by the removal of MB with maximum adsorption capacity reached to 268.98 mg/g. Kinetic measurements could be more representative by pseudo-first-order model and this means that the sorption process is supported by physical forces. Finally, the effects of inlet concentrations and bed thickness on the migration of MB front were simulated in an efficient manner by COMSOL Multiphysics 3.5a package with root mean squared errors not in excess of 0.152.

Characterization of Chemical Components in Organs Emissions of Two Salvia dominica L. Populations from Jordan.

The current investigation reports the chemical composition of volatile organic compounds emitted from the different aerial organs of two populations of Salvia dominica L. from Jordan collected from Mediterranean and Irano-Turanian bio-geographical zones. Oxygenated monoterpenes dominated the emission profiles of most organs from the two populations but with variable qualitative and quantitative differences. Mediterranean samples contained higher content of oxygenated monoterpenes (stems: 88.37%, leaves 89.95%, pre-flowering buds 67.14%, fully opened flowers 79.43%, sepals 90.93% and petals 92.25%) as compared to those from Irano-Turanian origin (range 39.85% to 75.06%). trans-Sabinene hydrate dominated the emission profiles of all organs from Irano-Turanian zone (range 38.54% to 73.24%) in addition to the stem, sepal and petal samples from the Mediterranean zone (51.37% to 86.98%). The other organs from the Mediterranean zone were dominated by α-terpenyl acetate (27.66-54.87%). Cluster and Principle Component statistical analysis classified the two populations into two clusters based on their origin. The current study evidenced the different VOCs composition in the two populations, that was mainly related to climatic and environmental conditions and suggested the presence of two ecotypes of S. dominica L.in Jordan.

Reconstruction of severe burn contractures of the upper lip in males using a pedicled superficial temporal artery hair-bearing flap. Two case reports.

INTRODUCTION: Severe burn contractures of the upper lip are usually treated either with full thickness skin grafts or flaps. Most authors recommend the free radial forearm flap as the flap of choice. In males, another free flap option is the use of the superficial temporal artery hair-bearing free flap. CASE REPORTS: In this report, we demonstrate that the superficial temporal artery hair-bearing flap may be used as a pedicle flap (rather than a free flap) for the reconstruction of severe upper lip burn contractures in males. We show our method of flap delay and design to ensure that the distal part of the flap will survive; and this will be demonstrated in two case reports. DISCUSSION: The pedicled superficial temporal artery flap is much simpler to execute than free flaps. CONCLUSIONS: Severe post burn contractures of the upper lip in males may be reconstructed using the pedicled superficial temporal artery hair-bearing flap. In order for the flap to reach the contralateral side of the lip, it will have to cross the midline in the scalp. We demonstrate our method of flap delay and design to ensure flap safety and viability. We also show that concurrent burn deformities in close proximity of the upper lip should be treated prior to upper lip reconstruction. Finally, we stress on the principle of reconstructing the entire skin of the upper lip as one aesthetic unit.

Aroma Profile of Two Populations of Salvia verbenaca Collected from Two Bio-Geographical Zones from Jordan.

The aroma emitted from the different organs of two Salvia verbenaca L. populations from Jordan were extracted by Solid Phase Micro-Extraction (SPME) and then analyzed by GC/MS. The emission profile of the stem, leaf and sepal samples from the Mediterranean zone (Al-Salt) was dominated by monoterpene hydrocarbons (68.0 %, 33.7 %, and 42.2 %, respectively). The emission profile of flowering parts including pre-flowering buds, fully expanded flowers and petals was dominated by oxygenated monoterpenes (58.6 %, 59.3 % and 87.1 %, respectively). The major constituent detected in these organs was trans-sabinene hydrate acetate (range 14.5 %-87.0 %). On the other hand, samples collected from Irano-Turanian zone showed different emission patterns. While the stems, leaves and petal emissions were dominated by sesquiterpene hydrocarbons (54.9 %, 76.8 % and 52.6 %, respectively), monoterpene hydrocarbons dominated the emission profiles of the pre-flowering buds (75.1 %) and fully expanded flowers (73.6 %). Petals emissions were characterized by high concentrations of oxygenated monoterpenes (58.8 %). Notably, trans-sabinene hydrate dominated most organs emissions except for leaves (range 20.0 %-58.8 %). Principle Component Analysis (PCA) and Cluster Analysis (CA) revealed two different clusters related to the two different geographical zones. The current investigation revealed two ecotypes of S. verbenaca that could result in two different chemotypes. Trans-sabinene hydrate acetate and trans-sabinene hydrate are suggested compounds for identifying these two chemotypes.

Chemical constituents of Fumaria densiflora and the effects of some isolated spirobenzylisoquinoline alkaloids on murine isolated ileum and perfused heart.

Twenty-two alkaloids, were isolated from Fumaria densiflora. Two of these alkaloids, N-methyl-5-hydroxystylopine chloride and fumaricine N-oxide, were isolated for the first time from natural sources. Parfumine and fumaritine, in concentrations ranging from 3 × 10-7 to 9 × 10-4 M, caused concentration-dependent relaxation of ileum longitudinal segment. Also, parfumine and fumaritine in concentrations ranging from 3 × 10-4 to 9 × 10-2 M, caused concentration - dependent decrease in heart rate of the isolated perfused heart. A concentration of parfumine of 3 × 10-2 M increased but a higher concentration (9 × 10-2 M) decreased the amplitude of contraction of the isolated perfused heart. On the other hand, fumaritine, in concentrations ranging from 3 × 10-4 to 3 × 10-2 M, caused concentration - dependent increase, but a higher concentration (9 × 10-2 M) caused a decrease in the amplitude of contraction of the isolated perfused heart.[Formula: see text].

These included: luteolin-3'-methyl ether (1), indole-3-carboxyaldehyde (2), p-hydroxybenzaldehyde (3), tricin (4), apigenin (5), methyl isoferuloyl-7-(3,4-dihydroxyphenyl) lactate (6), methyl rosmarinate (7), rosmarinic acid (8), salvigenin (9), ß-sitosterol (10), 3ß, 28-dihydroxyurs-12-ene (11), cirsilineol (12), 2,3-dihydroxyurs-12-en-28-oic acid (13), ß-sitosteryl glucoside (14), and tormentic acid (15). Compounds 6 and 7 exhibited strong radical scavenging and chelating activities as compared to α-tocopherol and ascorbic acid, compound 7 showed a 2-fold greater antioxidant activity as compared to compound 6. Furthermore, low doses of compounds 6 and 7 were able to inhibit the growth of leukemic (HL-60, Jurkat, K562 and CCRF-SB) and solid tumor cells (MCF-7, MDA-MB-231 and Caco-2). Compound 7 showed a ca. 3-4-fold stronger cytotoxicity against the tested cells as compared to compound 6.

Serological survey for Brucella antibodies in donkeys of north-eastern Nigeria.

A cross-sectional epidemiological study was conducted to determine seroprevalence and risk factors influencing the presence of Brucella antibodies in donkeys of Borno State, north-eastern Nigeria. The study aimed at providing baseline information that may be used in planning a control policy against equine brucellosis. Blood samples were collected from 601 donkeys, comprised of 374 males and 227 females from the six agricultural zones of the state between March 2013 and September 2014. The sera obtained were tested for Brucella antibodies using Rose Bengal plate test (RBPT) and competitive enzyme-linked immunosorbent assay (cELISA). Of the 601 donkeys tested, 43 (7.2%) and 40 (6.7%) were seropositive by RBPT and cELISA, respectively. A seroprevalence of 8.6% was obtained in male and 3.5% in female donkeys. According to age, the highest seroprevalence of 9.6% was obtained from donkeys of age group 4-6 years. With respect to pregnancy status, a higher seroprevalence (6.8%) was obtained from pregnant donkeys compared to 3.8% obtained from the non-pregnant ones. There were statistically significant associations between the presence of antibodies and sex (p < 0.05) and the presence of antibodies and age (p < 0.05) of the studied donkeys. However, no statistically significant association (p > 0.05) was observed between the pregnancy status and presence of antibodies. The study concludes that Brucella infection is present in donkeys in all the agricultural zones of the state. The relatively high seroprevalence (7.2%) obtained is of public health concern because of the close interaction between donkeys, ruminants, and humans in the study area.
