Background to Study: Lead (Pb) is ubiquitous in the environment and toxic. It has many negative effects on many organs and induces biochemical, physiological, and behavioural alterations on the brain. Monodora myristica is a calabash nutmeg belonging to the family of Annonaceae.It is a rich source of flavonoids which have been shown to exhibit both antioxi-dant and anti-inflammatory properties. We evaluated the protective role of Monodora myristica on lead-induced toxicity in D. melanogaster in this study

Backgrounds: Neurolathyrism is a disease, which is linked with the consumption of Lathyrus sativus ( L. sativusi) pulse that contain the neurotoxin-beta-N-oxalyl-L-alpha-beta-diamino propionic acid (beta-ODAP). Patients with Lathyrisum suffer with gradual enhancement in spasticity and bony changes, which are responsible for appearing the crippling condition throughout life. Objective: The present study has been done as to establish the present situation of L. sativusi consumption and Lathyrisum. Materials and Methods:We performed the survey in the village of Mohammadabad Block of Gazipur district in Eastern Uttar Pradesh (a state with maximum population in India) which have population of million, and L. sativusi is the main pulse of the year, which sustains the economy of these populations. Results:Out of 21,234 subjects L. sativusi eating population for more than 10 years, none had Lathyrisum. On contrary, to popular belief, this population enjoys various dishes made by L. sativusi pulse which in popular are local delicacy. Conclusions:There is no evidence of L. sativusi causing Lathyrisum in 2021. On contrary, L. sativusi pulses have become an inheriting part of the food habits in these populations.

Psychoactive substances, also known as psychotropic substances are substances that alter the mental state of a person by affecting the way the nervous system and brain work [1]. Psychoactive substances can cause intoxication and this is generally the major reason why most individuals engage in their use. Individuals who take psychoactive substances experience changes in brain function which alter their mood, consciousness, and/or perceptions. Psychoactive substances are present in different medications, alcohol, plants, and animals [2], many, but not all of which are addictive [1]. The most common psychoactive drugs used by people to alter their mental state are caffeine and alcohol [3]. Although they are available legally, yet, they are harmful both psychologically and physically when used in excess. Usually, the decision of how and when to use these psychoactive drugs is left to the individuals [3], however, in certain situations, the drugs are used for exploitation of others by the alteration of their mental state. For example, Rohypnol has been used as a date-rape [4]. Some of the psychoactive drugs are very unpleasant making the users quit their use. This is the case in certain classic psychedelics (e.g., psilocybin), powerful dissociatives (e.g., Salvia divinorum), and deliriants (e.g., Jimson weed) [5]. Addiction and dependence resulting from the misuse of psychoactive drugs have led to moral debate and legal measures, while governmental controls on prescription, supply, and manufacture have been efforts made to minimize the additive use of these drugs. Also, ethical concerns exist about the marketing of these drugs by manufacturers and their clinical over-use. However, in some countries, there are ongoing popular campaigns geared towards legalizing and decriminalizing the use of some recreational drugs such as cannabis. Many individual, genetic and environmental factors have been reported to work individually or synergistically to decrease or increase the probability that an individual will use a psychoactive drug and to what extent [6]. This review aimed at updating information on the different uses of various psychoactive drugs by humans, the different effects on the biological system, and their reported DNA damaging potential in simulated and real-life scenarios.

The aim of this research was to assess the biochar ability to protect the photosynthesis process face to Cd contamination, especially, when nitrogen fertilizer was added at adequate amount. Culture of tomato seedlings was conducted on pots containing soil added with different portion of biochar (0, 3.5 and 7%) and nitrogen (3 or 6g NH4NO3). Irrigation was done by water (control condition) or Cd solution (150µM). Data showed that regardless presence of Cd, synchronously addition of high nitrogen fertilizer (6g) and biochar (7%) in the culture medium resulted in fresh matter production, photosynthetic pigment (Chlorophyll a) and mineral elements content enhancement. Similar observation was shown concerning the mineral nutrition (nitrogen, phosphorus and potassium contents).

Taxus baccata is one of the most poisonous trees in the world. It contains taxanes and toxic alkaloids: the most dangerous one is the taxine. It is a fairly common plant in our environment and could be extremely dangerous; however, yew poisoning is quite rare. Cases may occur by voluntary or accidental ingestion. Therefore, the rapid orientation and diagnosis of suspected episode are important, in order to treat it quickly.

Gemcitabine is a pyrimidine analog and cisplatin is a platinum agent, they are usually combined to form a chemotherapeutic doublet used to treat different types of oncological cancers, including non-small cell lung cancer (NSCLC). Although these agents are not known to cause such events, few cases related to possible cardiotoxicity side effects have been reported ; including angina, chronic heart failure, arrhythmias, and cardiac ischemia. A 52-year-old African male presented with Stage IV lung adenocarcinoma metastatic to the bone, pleura and lymph node, EGFR wild type. Patient has a history of hypertension, diabetes, and atrial fibrillation and on rate control medications. He was treated initially with cisplatin-gemcitabine, after which he developed cardiomyopathy.

The use of real explosive materials for canine training involves inherent dangers, toxicity risks exposure, and often limited availability of the training material all of which may affect the reliable training of canine teams. For this reason, the development of a training aid suitable for daily operations is beneficial to provide safe and effective explosive detection training that can provide for enhanced detection capabilities.

Methamphetamine is one of the most commonly abused illegal stimulants and causes the release of dopamine, norepinephrine and serotonin. These neurotransmitters trigger vasospasm, causing persistent tachycardia, hypertension, and direct myocardial toxicity. Moderate usage of methamphetamine can increase cardiac output and myocardial contractility. However, larger doses can cause depression of the myocardium.
