Abstract Background Minocycline is a clinically available synthetic tetracycline derivative with anti-inflammatory and antibiotic properties. The majority of studies show that minocycline can reduce tissue damage and improve functional recovery following central nervous system injuries, mainly attributed to the drug’s direct anti-inflammatory, anti-oxidative, and neuroprotective properties. Surprisingly the consequences of minocycline’s antibiotic (i.e., antibacterial) effects on the gut microbiota and systemic immune response after spinal cord injury have largely been ignored despite their links to changes in mental health and immune suppression. Methods Here, we sought to determine minocycline’s effect on spinal cord injury-induced changes in the microbiota-immune axis using a cervical contusion injury in female Lewis rats. We investigated a group that received minocycline following spinal cord injury (immediately after injury for 7 days), an untreated spinal cord injury group, an untreated uninjured group, and an uninjured group that received minocycline. Plasma levels of cytokines/chemokines and fecal microbiota composition (using 16s rRNA sequencing) were monitored for 4 weeks following spinal cord injury as measures of the microbiota-immune axis. Additionally, motor recovery and anxiety-like behavior were assessed throughout the study, and microglial activation was analyzed immediately rostral to, caudal to, and at the lesion epicenter. Results We found that minocycline had a profound acute effect on the microbiota diversity and composition, which was paralleled by the subsequent normalization of spinal cord injury-induced suppression of cytokines/chemokines. Importantly, gut dysbiosis following spinal cord injury has been linked to the development of anxiety-like behavior, which was also decreased by minocycline. Furthermore, although minocycline attenuated spinal cord injury-induced microglial activation, it did not affect the lesion size or promote measurable motor recovery. Conclusion We show that minocycline’s microbiota effects precede its long-term effects on systemic cytokines and chemokines following spinal cord injury. These results provide an exciting new target of minocycline as a therapeutic for central nervous system diseases and injuries.

Benzoxazoles being structurally similar to bases adenine and guanine interact with biomolecules present in living systems. These compounds possess antimicrobial, central nervous system activities, antihyperglycemic potentiating activity, analgesic, and anti-inflammatory activity. It can also be used as starting material for other bioactive molecules. Modifications in structure and the biological profiles of new generations of benzoxazoles were found to be more potent with enhanced biological activity. Considering all these, we have prepared this review and discussed the synthesis and biological activities of benzoxazoles.

Lavandulae aetheroleum, the oil, was obtained by vapor condensation from the flower of Lavandula angustifolia Mill. or Lavandula intermedia Loisel (Lamiaceae) plant. Other names of Lavandulae aetheroleum oil are Al birri, common or English lavender. The Lavandula angustifolia Mill. or Lavandula intermedia Loisel plant is spreading in the Mediterranean, southern Europe, Bulgaria, Russia, and USA. The Lavandula angustifolia Mill. or Lavandula intermedia Loisel plant, is an odor shrub with 1-2 m in height. The oil is a clear, colorless, or pale yellow. The gas chromatography studies reported the following percentage of the major chemical constituents in the oil: linalyl acetate (25-46%), linalool (20-45%), terpinen-4-ol (1.2-6.0%), lavendulyl acetate (> 1.0%), 1,8-cineole (1,8-cineol, cineol, cineole, eucalyptol) (< 2.5%), 3-octanone (< 2.5%), camphor (< 1.2%), limonene (< 1.0%), and α-terpineol (< 2.0%). Medicinal applications of the oil include the treatment of restlessness, anxiety, cardiovascular disorders, insomnia, and gastrointestinal disorders, burns, diarrhea, headache, sore throats, and wounds. Pharmacological effects include experimental and clinical pharmacology. Experimental pharmacology includes anesthetic, anticonvulsant, sedative, anti-inflammatory, antimicrobial, antispasmodic, antispasmodic, central nervous system depressant effects. Clinical pharmacology includes anxiolytic, analgesic, and cardiovascular effects. The oil dose by inhalation = 0.06-0.2 ml/ 3 times/day while oil dose internally = 1-4 drops approximately 20-80 mg on a sugar cube per day. In conclusion, Lavandulae aetheroleum oil had an anesthetic, anticonvulsant, sedative, anti-inflammatory, antimicrobial, antispasmodic, antispasmodic, central nervous system depressant, anxiolytic, analgesic, and cardiovascular effects.

Myristica fragrans or nutmeg is a ground spice of the family Myristicaceae. Its tree has dark leaves mainly cultivated in Grenada, Malaysia, and Kerala. It is majorly a source of two spices derived from its fruit: nutmeg (jaiphal) from its seed and mace (javitri) from the covering of seed. The important bioactive constituents present in nutmeg include macelignan, carvacrol, myristicin, β-caryophyllene, β-pinene, α-pinene, p-cymene, and eugenol. Low doses of nutmeg do not cause any side effects whereas after consuming 5g toxic overdose occurs, and central nervous system (CNS) effects were induced after consuming 1 to 2 mg/kg b.wt. of nutmeg. Various therapeutic or medicinal applications were shown by nutmeg such as antioxidant, antimicrobial, aphrodisiac, anticancer, hepatoprotective, anti-inflammatory, antidepressant, and cardioprotective activity. This review chapter focuses on ethnobotany, phytochemistry, acceptable daily intake, and different pharmacological actions of this medicinal plant.

The findings reported in the Letter to the Editor authored by Bungener and Jouvent are consistent with results we have presented here (Castellon et al., 2000) and again underscore the importance of considering the potentially multifactorial nature of depression in many neurologic diseases/disorders. We have suggested, although the idea is hardly a new one, that depression in HIV/AIDS can be secondary to any of multiple potential etiologies. For example, it may be a direct central nervous system (CNS) consequence of infection (i.e., neurochemical and/or neuropathological changes), a result of increased exposure to social, medical, and financial stressors secondary to living with HIV, a reaction to multiple losses (e.g., bereavement, loss of instrumental capacity), or be an admixture of multiple etiological factors. The phenomenology of this disruption of mood, motivation, and affect may differ as a function of etiology/pathophysiology. We believe that a prominent amotivation/apathy syndrome may be a more pure manifestation of the CNS effects of HIV-1 infection than is the more heterogeneous construct of depression and therefore more closely associated with other putative measures of CNS integrity (e.g., neurocognitive performance).

Melatonin (MLT) is a powerful chronobiotic hormone that controls a multitude of circadian rhythms at several levels and, in recent times, has garnered considerable attention both from academia and industry. In several studies, MLT has been discussed as a potent neuroprotectant, anti-apoptotic, anti-inflammatory, and antioxidative agent with no serious undesired side effects. These characteristics raise hopes that it could be used in humans for central nervous system (CNS)-related disorders. MLT is mainly secreted in the mammalian pineal gland during the dark phase, and it is associated with circadian rhythms. However, the production of MLT is not only restricted to the pineal gland; it also occurs in the retina, Harderian glands, gut, ovary, testes, bone marrow, and lens. Although most studies are limited to investigating the role of MLT in the CNS and related disorders, we explored a considerable amount of the existing literature. The objectives of this comprehensive review were to evaluate the impact of MLT on the CNS from the published literature, specifically to address the biological functions and potential mechanism of action of MLT in the CNS. We document the effectiveness of MLT in various animal models of brain injury and its curative effects in humans. Furthermore, this review discusses the synthesis, biology, function, and role of MLT in brain damage, and as a neuroprotective, antioxidative, anti-inflammatory, and anticancer agent through a collection of experimental evidence. Finally, it focuses on the effect of MLT on several neurological diseases, particularly CNS-related injuries.

AbstractThe convergence of the HIV and SARS-CoV-2 pandemics is an emerging field of interest. In this review, we outline the central nervous system (CNS) effects of COVID-19 in the general population and how these effects may manifest in people with HIV (PWH). We discuss the hypothetical mechanisms through which SARS-CoV-2 could impact the CNS during both the acute and recovery phases of infection and the potential selective vulnerability of PWH to these effects as a result of epidemiologic, clinical, and biologic factors. Finally, we define key research questions and considerations for the investigation of CNS sequelae of COVID-19 in PWH.
