Hepatocellular carcinoma (HCC) is among the most prevalent and deadly cancers globally, with limited treatment options and poor prognosis in advanced stages. This study evaluated the therapeutic potential of methanol leaf extract of Annona senegalensis against diethylnitrosamine (DEN)-induced HCC in Wistar rats and investigated its antibacterial properties. Thirty-six male albino rats were allocated into six groups: Group I (normal control) received no treatment; Group II (negative control) was induced with HCC using DEN (50 mg/kg b.w., intraperitoneally) weekly for three weeks without therapy; Group III (positive control) received DEN followed by silymarin (100 mg/kg b.w.); while Groups IV, V, and VI received DEN followed by A. senegalensis extract at 200, 400, and 600 mg/kg b.w., respectively, administered orally for 14 days. Biochemical analysis showed that the extract significantly (p < 0.05) ameliorated DEN-induced hepatotoxicity, with the 400 mg/kg dose most effective in reducing AST (48.71 ± 1.21 IU/L) and ALT (20.74 ± 1.06 IU/L) compared to the negative control (69.52 ± 0.88 IU/L and 54.97 ± 1.54 IU/L, respectively). Hepatic synthetic function was restored, as indicated by increased total protein (6.37 ± 0.13 g/L) and albumin (5.11 ± 0.10 g/L). Histopathological analysis confirmed marked architectural recovery with reduced necrosis and inflammatory infiltration. The extract also demonstrated significant antibacterial activity, exhibiting dose-dependent inhibition zones against Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacteria, with effects comparable to standard antibiotics. These findings suggest that A. senegalensis leaf extract exerts hepatoprotective effects—likely through antioxidant, anti-inflammatory, and antiproliferative mechanisms—while also offering broad-spectrum antimicrobial benefits. The 400 mg/kg dose emerged as the most effective, highlighting its promise as a cost-effective complementary therapy for managing HCC and bacterial infections, particularly in resource-constrained settings. Further research should focus on isolating and characterizing the bioactive compounds and elucidating their mechanisms of action.

Although debates on abortion reform have intensified in Nigeria, limited attention has been paid to how partial legalization shapes youth perspectives and sexual and reproductive behaviors within specific sociocultural and religious contexts. This study examines how the limited legalization of abortion influences youth attitudes and behaviors in Adamawa State, with particular attention to demographic, cultural, and institutional factors, as well as the Catholic Church’s response to these changes. A qualitative approach was employed through interviews with health workers, clergy, and youths aged 18–25 from urban and rural areas of Adamawa State. Supplementary data were obtained from community forums, church outreach programs, and health service records, and the data were analyzed thematically to identify patterns in attitudes, behaviors, and institutional responses. The findings indicate a marked urban–rural divide, with urban youths reporting higher sexual activity, greater contraceptive use, and stronger support for reproductive autonomy. The study also found that the Catholic Church’s moral campaigns have had limited influence, particularly among urban youths who perceive religious teachings as less relevant to contemporary realities. In contrast, health workers were viewed as more trusted sources of guidance, while peers and media played a substantial role in shaping youth behavior. The study concludes that the evolving legal and cultural landscape in Adamawa State reflects a broader generational shift toward autonomy and informed decision-making among youths. These findings contribute to understanding the changing relationship between legal reform, religious influence, and youth reproductive behavior, and suggest that more balanced strategies integrating moral guidance, comprehensive education, and supportive policies are needed to promote healthy youth development in a changing society.

Microbial production of antimicrobial compounds remains a fundamental area of biotechnology and pharmaceutical development, and its efficiency is strongly influenced by the carbon source available in the growth medium, which functions not only as an energy substrate but also as a regulator of microbial metabolism and secondary metabolite synthesis. This study aimed to evaluate the effects of five carbon sources—glucose, lactose, sucrose, starch, and glycerol—on microbial biomass yield, strain-specific growth preferences, metabolic compatibility, antimicrobial potency, inhibition zones, and bioactive metabolite production. Seven microbial strains, including Streptomyces, Bacillus, Pseudomonas, Actinomyces, and Clostridium, were cultured in media supplemented with each carbon source. Biomass yield was measured gravimetrically, growth rate indices were calculated on a scale of 0–10, antimicrobial potency was assessed using zone of inhibition assays against S. aureus, E. coli, P. aeruginosa, and K. pneumoniae, and metabolite yield was quantified in mg/L using spectrophotometric analysis. All experiments were conducted in triplicate. The findings showed that glucose produced the highest biomass yield and growth rates across all strains, with Bacillus and Pseudomonas each scoring 10. Lactose demonstrated selective effectiveness, particularly for Streptomyces, whereas sucrose supported moderate growth and selective antimicrobial activity. In contrast, starch and glycerol consistently resulted in low biomass production and minimal antimicrobial potency. The zone of inhibition results further confirmed that glucose and lactose were the most effective substrates, with inhibition zones exceeding 20 mm. Similarly, metabolite yield was highest with glucose (120 ± 5.4 mg/L) and lactose (115 ± 4.9 mg/L), while glycerol produced the lowest yield (30 ± 1.5 mg/L). The study concludes that carbon source selection plays a critical role in microbial proliferation and antimicrobial compound production, with glucose and lactose emerging as the most suitable substrates for broad-spectrum antimicrobial activity and high metabolite yield. These findings contribute practical evidence for optimizing fermentation strategies according to microbial metabolic profiles to enhance antimicrobial synthesis.

While many methods exist for measuring the impact of AIDS, treatment remedy the human development approach focuses on people rather than medical or economic indicators. Human Development Index captures three basic dimensions of human development: a long and healthy life—measured by life expectancy at birth; knowledge—measured by adult literacy and school enrolment; and standard of living—measured by per capita gross domestic product. Thus, investigate the hepatoprotective activity of aqueous extract of Jatropha gossypiifolia seed in highly active antiretroviral therapy administered rats. Liver is a metabolically active organ responsible for many vital life functions. It performs many activities that are critical for survival. Due to its important activities, the liver is exposed to a number of insults and is one of the body's organs most subject to injury. In spite of tremendous advances in modern medicine, there are hardly any reliable drugs that protect the liver from damage and/or help in regeneration of hepatic cell. It is, therefore, necessary to search for effective and safe herbal drugs for the treatment of liver disease to replace currently used drugs of doubtful efficacy and safety. Hence, the need to evaluate the aqueous extract of Jatropha gossypiifolia seed in highly active antiretroviral therapy (Lamivudine, Zidovudine and Efavirenz) administered rats. Sixty rats weighed between 150-200g were randomly divided into six groups and each group comprised of ten rats. Rats in group I were administered with distilled water. Rats in group II were administered with highly active antiretroviral therapy only. Rats in groups III - VI were administered 100, 200, 400 and 600 mg/kg Jatropha gossypiifolia seed plus highly active antiretroviral therapy respectively. The treatments were given orally for 28 consecutive days. On the 29th day, all rats were sacrificed under light diethyl ether anaesthesia; blood samples were collected for the assessment of biochemical parameters, while Serum levels of liver enzymes ALT, AST, ALP, and GGT were significantly (p<0.05) increased and albumin concentration was significantly decreased in animals treated with highly active antiretroviral therapy as compared to the normal control. Treatment of highly active antiretroviral therapy exposed animals with Jatropha gossypiifolia seed showed marked improvement in biochemical findings. Rise in liver enzymes was almost restored to normal in animals treated with Jatropha gossypiifolia seed. Jatropha gossypiifolia seed through its antioxidant activity effectively protects highly active antiretroviral therapy induced liver toxicity.

Liver cancer, particularly hepatocellular carcinoma (HCC), is a leading cause of mortality worldwide and is frequently associated with hematological complications such as anemia and impaired blood clotting. This study evaluated the hematoprotective effects of methanol stem-bark extract of Annona senegalensis in rats with diethylnitrosamine (DEN)-induced HCC. Fifty-four male rats were allocated into six groups: a normal control group, a DEN-induced group without treatment, a positive control group treated with silymarin, and three treatment groups administered varying doses of A. senegalensis extract. Hematological parameters assessed included red blood cells (RBC), hemoglobin (HGB), white blood cells (WBC), hematocrit (HCT), and platelets (PLT). DEN induction significantly reduced RBC, HGB, and PLT levels, indicating anemia and coagulation impairment. Treatment with A. senegalensis, particularly at 400 mg/kg, markedly improved these hematological indices, suggesting a restorative effect on blood parameters. The protective role of the extract may be attributed to its bioactive constituents, such as flavonoids, alkaloids, and tannins, known for their antioxidant and anti-inflammatory activities. These findings suggest that A. senegalensis possesses promising hematoprotective potential in the management of blood-related complications associated with liver cancer. Further research, including mechanistic studies and clinical trials, is warranted to validate its safety and therapeutic efficacy in humans.

Achyranthes aspera (Amaranthaceae) is an important medicinal herb found as a weed throughout Nigeria. Though almost all of its parts are used in traditional systems of medicines, leaves, seeds, roots and shoots are the most important parts which are used medicinally. The present article gives an account of updated information on its phytochemical and pharmacological properties. The Human immunodeficiency virus (HIV) infection is still contributing significantly in morbidities and mortalities in the world today. The drugs normally used to treat the infection are costly, toxic, and less effective due to resistance by HIV. Thus, the assessment of gp120-CD4 binding inhibition potential of Achyranthes aspera leaves extract was conducted using gp120-CD4 capture ELISA kits. Aqueous, methanol, and petroleum ether extracts were prepared at 1000, 500 and 250 μg/ml and tested for gp120-CD4 binding inhibition. Sub-cute toxicity assay was done using albino rats; Biochemical parameters including alanine amino transferase (ALT), aspartate amino transferase (AST) and alkaline phosphatase (ALP) as well as bilirubin for liver and urea, electrolytes and creatinine for kidney functions were evaluated. The results of the effect of crude aqueous, methanol and petroleum ether Achyranthes aspera leaves extract against gp120-CD4 showed inhibition ranging from 1.4 – 17.2 %. with 1000 μg/ml showing highest percentage of inhibition. There was no significant difference (P = 0.862) in terms of percentage inhibition between the three concentrations tested. Methanol extract demonstrated the highest percentage inhibition of gp120-CD4 bindings (17.2 %). No significant difference (P = 0.124) between the three extracts against gp-120-CD4 bindings was observed. The results of the sub-acute toxicity study have shown that, there were no physical changes in animals treated with 500 mg/kg of all the extracts. The result of liver function test revealed that, ALT, AST and ALP were within the normal range (12U/L) for both the high and low concentrations of the extracts including the control. Also result for total protein, albumin, globulin for the test albino rats and that of the control rat were found to be within the normal range 5.1-6.1, 4.2-5.3, and 3.1-3.8 g/dl respectively. For serum electrolyte level, sodium and potassium ions for the various concentrations of the extracts tested and control were also found to be within normal range. The result of kidney function test revealed that, urea, creatinine and direct and total bilirubin of the rats tested and control were all found to be within normal range. In conclusion, ether Achyranthes aspera leaves extract possessed some levels of HIV-1 gp120-CD4 binding inhibition potentials and the extracts was found to be non-toxic at 250 and 500mg/ kg body weight. It can be recommended that, the bioactive compounds should therefore be isolated and tested for gp120-CD4 binding inhibition activity.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide, frequently linked to exposure to chemical carcinogens such as diethylnitrosamine (DEN). Medicinal plants have emerged as promising sources of bioactive compounds with potential anticancer and antimicrobial properties. This study evaluated the therapeutic potential of methanol stem-bark extract of Annona senegalensis against DEN-induced hepatocellular carcinoma and selected bacterial pathogens. Fifty-four male albino rats were allocated into six groups, with hepatocarcinogenesis induced by DEN, followed by a 14-day treatment with varying doses of the extract. Hepatoprotective effects were assessed using liver enzyme markers and serum protein levels, while antibacterial activity was determined via disc diffusion assays against Staphylococcus aureus and Escherichia coli. Results demonstrated that the extract significantly reduced liver enzyme levels (ALT, AST, ALP) and improved serum proteins (total protein and albumin) at higher doses (400 and 600 mg/kg), indicating hepatoprotective potential. Bilirubin levels also improved, suggesting reduced liver stress. Antibacterial evaluation revealed dose-dependent activity, with strong inhibition against S. aureus comparable to tetracycline at 200 µg/mL, and moderate efficacy against E. coli. These findings highlight the dual therapeutic potential of A. senegalensis stem-bark extract as both a hepatoprotective and antibacterial agent. Future studies are recommended to isolate and characterize the bioactive compounds responsible for these effects and to expand antibacterial evaluation to a wider spectrum of pathogens.
