Abstract
The immune-modulatory effects of black seeds (Nigella sativa seeds, NSS) are well documented, but the overall in vivo impact of this important natural medicinal product on immune system function has yet to be established. Here we systematically reviewed and meta-analyzed the effects of NSS on humoral [serum titers of immunoglobulins including IgG, IgM, anti-Newcastle virus disease (anti-NDV), and sheep red blood cell antigen (anti-SRBC)] and cellular immunity [total white blood cell (WBC) count and percentages of monocytes, lymphocytes, basophils, neutrophils, and eosinophils] in healthy animals. The PubMed, ScienceDirect, Web of Science, and Scopus databases were searched according to predefined eligibility criteria. Meta-analyses were performed to estimate the final effect size using RevMan software. Seventeen animal studies were eligible for analysis. For humoral immunity, the overall pooled effect size (ES) of NSS on serum titers of IgM and anti-NVD antibodies was not significantly different [mean difference (MD) 75.27, 95% CI: -44.76 to 195.30, p = 0.22 (I2 = 89%, p = 0.003), and -0.01, 95% CI: -0.27 to 0.25, p = 0.94 (I2 = 74%, p = 0.02), respectively]. However, NSS significantly increased serum titers of IgG and anti-SRBC antibodies [MD 3.30, 95% CI: 2.27 to 4.32, p = 0.00001 (I2 = 0%, p = 0.97), and 1.15, 95% CI: 0.74 to 1.56, p = 0.00001 (I2 = 0%, p = 0.43), respectively]. For cellular immunity, the ES of NSS on WBCs, monocytes, and lymphocytes were not significantly different [MD 0.29, 95% CI: -0.55 to 1.13, p = 0.50, (I2 = 14%, p = 0.32), - 0.01, 95% CI: -0.45 to 0.44, p = 0.97 (I2 = 0%, p = 0.77), and 4.73, 95% CI: -7.13 to 16.59, p = 0.43, (I2 = 99%, p = 0.00001), respectively]. In conclusion, black seeds enhance humoral immunity in healthy animals but do not affect cellular immunity.

Abstract
The recent outbreaks of Nipah viral infection were associated with severe respiratory illness, lethal encephalitis, and an extremely high mortality rate. As there are no approved antiviral medications, patients with NiV infections are currently treated with repurposed or investigational antivirals and supportive care. This review examines the potential health benefits of N. sativa in the treatment of NiV infection. To identify relevant studies, the literature was searched in online databases like Medline/PubMed, Google Scholar, Science Direct, and reference lists. Through its antiviral, anti-inflammatory, antioxidant, anticonvulsant, immunomodulatory, bronchodilatory, and other properties, a number of studies have demonstrated that N. sativa is effective against a variety of viral infections, inflammatory conditions, neurological and respiratory illnesses, and other conditions. As a result, in the treatment of NiV-infected patients, N. sativa could be added as an adjuvant treatment alongside repurposed or investigational antivirals and supportive care. The efficacy of N. sativa in the treatment of NiV infection will be determined by the results of upcoming randomized controlled clinical trials.

Abstract
BACKGROUND Some individuals may experience symptoms persisting for many months after the recovery from COVID-19 and patients with Long COVID are managed mainly with symptomatic treatment and supportive care. OBJECTIVE This review article focuses on the beneficial effects of black seeds (Nigella Sativa) in the management of long COVID and persistent COVID symptoms. METHODS The literature was searched in databases such as LitCOVID, Web of Science, Google Scholar, bioRxiv, medRxiv, Science Direct, EBSCO, Scopus, Embase, and reference lists to identify studies, which evaluated various effects of black seeds (N. sativa) related to signs and symptoms of Long COVID. RESULTS Black seeds (N. sativa) have shown potential anti-COVID, antiviral, anti-inflammatory, antioxidant, immunomodulatory, antihypertensive, anti-obesity, antidiabetic, antihyperlipidemic, and antiasthmatic properties in various clinical, animal, in-vitro, in-vivo, and in-silico studies, which would help the patients recovered from COVID to mitigate Long COVID complications. CONCLUSION Patients experiencing Long COVID may use black seeds (N. sativa) as adjunctive therapy in combination with symptomatic treatment and supportive care to prevent further deterioration and hospitalization. The safety and efficacy of N. sativa in patients with Long-COVID would further be established by future randomized controlled clinical trials.

Abstract
BACKGROUND Leukemia is the most common pediatric malignancy. It affects bone marrow cells especially lymphoid cell precursor. Leukemia is treated mainly by chemotherapy. Doxorubicin is a well-established chemotherapeutic agent included in treatment protocols of acute lymphoblastic leukemia. Its efficacy is often limited by its cardiotoxic side effects. Many studies are directed to overcome this problem. Black seed oil was found to have a potent cardioprotective effect.Aim of the study: To assess the protective role of black seed oil against doxorubicin-induced cardiotoxicity in children with acute lymphoblastic leukemia. SUBJECTS AND METHODS This study was carried out on 40 children with acute lymphoblastic leukemia including 20 patients under doxorubicin therapy and black seed oil 80 mg/kg/dose divided into 3 doses starting at the same moment of beginning of doxorubicin infusion therapy and continued for 1 week after each doxorubicin dose [group I] and 20 patients under doxorubicin and placebo for 1 week after each doxorubicin dose [group II]. They underwent conventional echo-Doppler measures of left ventricular systolic and diastolic functions and pulsed wave tissue Doppler of lateral mitral annulus. RESULTS No significant differences were found in parameters of electrocardiograph including S-T segment and Q-T interval either before or after doxorubicin therapy. No significant differences in echocardiographic parameters were found between group I and group II before therapy. Non-significant changes in parameters of diastolic function [E/A ratio or e/a ratio] were found after doxorubicin therapy in group I and II, but there were significant reduction in parameters of systolic function [EF, FS and s wave] after doxorubicin therapy more in group II than group I.Conclusion and recommendation: From this study, we concluded that: Black seed oil improves some cardiac side effects of doxorubicin as shown by better systolic functions in children with acute lymphoblastic leukemia who were treated with Doxorubicin and black seed (group I) than in children with acute lymphoblastic leukemia who were treated with doxorubicin alone with no black seeds (group II), and therefore multi center studies is recommended to be done before we can recommend the use of black seed oil as an adjuvant therapy in patients with acute lymphoblastic leukemia under doxorubicin-based treatment protocol.

Abstract
Nigella sativa (N. sativa) (Family Ranunculaceae) is a widely used medicinal plant throughout the world. It is very popular in various traditional systems of medicine like Unani and Tibb, Ayurveda and Siddha. Seeds and oil have a long history of folklore usage in various systems of medicines and food. The seeds of N. sativa have been widely used in the treatment of different diseases and ailments. In Islamic literature, it is considered as one of the greatest forms of healing medicine. It has been recommended for using on regular basis in Tibb-e-Nabwi (Prophetic Medicine). It has been widely used as antihypertensive, liver tonics, diuretics, digestive, anti-diarrheal, appetite stimulant, analgesics, anti-bacterial and in skin disorders. Extensive studies on N. sativa have been carried out by various researchers and a wide spectrum of its pharmacological actions have been explored which may include antidiabetic, anticancer, immunomodulator, analgesic, antimicrobial, anti-inflammatory, spasmolytic, bronchodilator, hepato-protective, renal protective, gastro-protective, antioxidant properties, etc. Due to its miraculous power of healing, N. sativa has got the place among the top ranked evidence based herbal medicines. This is also revealed that most of the therapeutic properties of this plant are due to the presence of thymoquinone which is major bioactive component of the essential oil. The present review is an effort to provide a detailed survey of the literature on scientific researches of pharmacognostical characteristics, chemical composition and pharmacological activities of the seeds of this plant.

Abstract
Background and Aim: The atherogenic pattern of dyslipidemia associated with type 2 diabetes mellitus (DM) has been increasingly discussed. We have recently reported a hypoglycemic effect of Nigella sativa (NS) seeds in patients with type 2 DM. In this study we sought to assess the impact of NS seeds on lipid profile in type 2 diabetic patients. Patients and Method: A total of 94 patients with type 2 DM were recruited and divided into 3 dose groups. Capsules containing NS were administered orally in a dose of 1, 2, and 3 g/day for 12 weeks. All patients were subjected to measurement of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) before treatment and 4, 8, and 12 weeks thereafter. Results: Patients receiving 1 g/day NS seeds for 12 weeks (group 1) showed nonsignificant changes in all the parameters except for a significant increase in HDL-c after 4 weeks of treatment. However, patients ingested 2 g/day NS displayed a significant decline in TC, TG, and LDL-c, and a significant elevation in HDL-c/LDL-c, compared with their baseline data and to group 1 patients. Increasing NS dose to 3 g/day failed to show any increase in the hypolipdemic effect produced by the 2 g/day dose. Conclusion: NS supplementation at a dose of 2 g/day for 12 weeks may improve the dyslipidemia associated with type 2 diabetic patients. Therefore, NS is a potential protective natural agent against atherosclerosis and cardiovascular complications in these patients.
