Indi Gregory was an 8-month-old English baby who passed away during the night between November 12 and 13, 2023. She suffered from mitochondrial DNA depletion syndrome in its encephalomyopathic form, a rare and severe neurometabolic disorder. In this condition, the mitochondria in her cells did not produce enough energy, preventing the proper development of her body, particularly her brain and heart. The disease is incurable and typically leads to death within the first two years of life, with treatments only able to alleviate symptoms. Discovered in 2013, the disease is caused by mutations in the SLC25A1 gene on chromosome 22, which is responsible for producing the mitochondrial citrate transporter. It is a recessive genetic disorder that manifests when a child inherits two copies of the mutated gene from their parents. If both parents are carriers, each child has a 25% chance of being affected, a 50% chance of being a healthy carrier, and a 25% chance of being healthy and not a carrier of the mutation. The disorder is progressive and presents with severe encephalopathy, seizures from birth, respiratory failure, and brain malformations. [ABSTRACT FROM AUTHOR]

Ephedra species are among the most popular herbs used in traditional medicine for a long time. The ancient Chinese medical book "Treatise on Febrile Diseases" refers to the classic traditional Chinese medicine prescription Ge Gen decoction, which consists of seven herbs, including an Ephedra species. Ephedra species are utilized all over the world to treat symptoms of the common cold and coughs, and to combat major human diseases, such as asthma, cancers, diabetes, cardiovascular and digestive disorders, and microbial infections. This study aimed at identifying specific Ephedra species used traditionally in Morocco for therapeutic purposes. The plant parts, their preparation process, and the treated pathologies were identified and analyzed. The results revealed five ethnobotanically important species of Ephedra: Ephedra alata Decne, Ephedra altissima Desf., Ephedra distachya L., Ephedra fragilis Desf., and Ephedra nebrodensis Tineo. These species are used traditionally in Morocco for treating people with diabetes, cancer, rheumatism, cold and asthma, hypertension, influenza virus infection, and respiratory ailments. In addition, they are occasionally used as calefacient agents, to regulate weight, or for capillary care. Few studies have underlined the antibacterial and antioxidant activities of some of these Moroccan Ephedra species, but little information is available regarding the natural products at the origin of the bioactivities. Further phytochemical investigations and clinical data are encouraged to better support the use of these plants. [ABSTRACT FROM AUTHOR]
