Biobased content analysis is a well-established, analytically independent, standardized method to determine the biobased content of fuels and plastics, based on differences of the specific radiocarbon (14C) activity of fossil and recent biogenic compounds. This biogenic content analysis can be useful for the producers as a quality assurance tool, for the customers as feedback about the truly biobased products and for the control organizations as an independent analytical tool to prove the biological origin. More than 100 commercially available foods, cosmetics, and drug samples have been used for biobased carbon content analysis by accelerator mass spectrometry (AMS) 14C measurement to demonstrate the potential of this technique. Our results show that this measurement technique is a unique tool for the determination of biocontent in foodstuff and medical products. Most of the tested materials were nearly or completely biobased (≥ 98 pMC), and no completely fossil-based final product was detected. The lowest biogenic compound was measured in a vanilla aroma flavor. In 45 of the 102 samples selected a wide range (2–98%) presented fossil-based carbon content. The method can be applied for monitoring raw materials and final products for biobased content in the industry and consumer protection as well.

The emergence of the COVID-19 pandemic has presented the addiction services with an unprecedented set of challenges. Opioid users are particularly vulnerable because of their high level of pre-existing health problems and lifestyle factors. In order to minimise their risks to self and to others in the current Covid-19 crisis, addiction services sought to urgently identify vulnerable individuals, and induct them into opioid substitution treatment (OST) promptly. Additionally, several guidelines were created and regularly updated by the health and safety executive (HSE) for any healthcare staff working with opioid users. These include guidance documents, to facilitate prompt induction of patients onto the OST programme, the prescribing of naloxone to all patients at risk of overdose, eConsultation, medication management for those in self-isolation, and the delivery of injecting equipment. The guidance documents and resources will provide a template for a new way of working for the sector during these challenging times and into the future.

The association of leishmaniasis and malignancies in human and animal models has been highlighted in recent years. The misdiagnosis of coexistence of leishmaniasis and cancer and the use of common drugs in the treatment of such diseases prompt us to further survey the molecular biology of Leishmania parasites and cancer cells. The information regarding common expressed proteins, as possible therapeutic targets, in Leishmania parasites and cancer cells is scarce. Therefore, the current study reviews proteins, and investigates the regulation and functions of several key proteins in Leishmania parasites and cancer cells. The up- and down-regulations of such proteins were mostly related to survival, development, pathogenicity, metabolic pathways and vital signalling in Leishmania parasites and cancer cells. The presence of common expressed proteins in Leishmania parasites and cancer cells reveals valuable information regarding the possible shared mechanisms of pathogenicity and opportunities for therapeutic targeting in leishmaniasis and cancers in the future.

Forty-five cases of psychotic patients with admission urinalysis positive for cannabis were compared with psychotic controls without evidence of cannabis use. Cases and controls were matched for age, sex and year of admission, and were compared for socio-demographic data, circumstances of admission, diagnosis, and symptoms at admission. Three differences were found: cases were more likely to be Afro-Caribbean than white (P = 0.01), to manifest incoherence of speech (P= 0.02) and agitation (P= 0.01). In other respects the case and control groups were indistinguishable, and no pattern of symptoms characterised the “cannabis psychosis“group. These findings do not support the view that “cannabis psychosis” has a distinct psycho-phenomenological pattern Epidemiological studies are required to further clarify the association for psychotic patients between Afro-Caribbean ethnic groups and the likelihood of having a positive urine test for cannabis.

Little information is available on the use of brief psychotherapy among subjects with generalised anxiety disorder (GAD) within community mental health services. This study compared results among subjects treated with brief Adlerian psychodynamic psychotherapy (B-APP), those treated with medication (MED), or those who experienced combined treatment (COM). Symptomatology and occupational functioning were assessed using the Hamilton Anxiety and Depression scales (HAM-A; HAM-D), Clinical Global Impression (CGI), and Social and Occupational Functioning Assessment Scale (SOFAS) at intake (T1) and at 3, 6, and 12 months later (T3, T6, T12). The study sample included 87 patients with GAD (B-APP 34; MED 33; COM 20), and an ANOVA was applied for analysing repeated measures while controlling for personality disorder. After 6 months, CGI, HAM-A, HAM-D, and SOFAS scores significantly improved independently from the type of treatment. Subjects with personality disorders treated with B-APP exhibited superior results to those treated using other methods only in SOFAS scores at T6. These results were generally maintained at T12. Remission rates among subjects (HAM-A scores <7) varied between 55% (MED) and 74% (B-APP) at T6 and between 63% (MED) and 78% (COM) at T12; no significant differences appeared between the three treatment groups. A logistic regression model predicted anxiety remission only by CGI at T1. This paper discusses these results in relation to the use of brief psychotherapy within community mental health services.

The protozoan parasite Leishmania is endemic in large parts of the world which causes leishmaniasis. Its visceral form is fatal if not treated and is caused mostly by Leishmania donovani, Leishmania infantum and Leishmania chagasi. Given the difficulties linked to vector (sandfly) control and the lack of an effective vaccine, the control of leishmaniasis relies mostly on chemotherapy. Unfortunately, the prevalence of parasites becoming resistant to the first-line drug pentavalent antimony (SbV) is increasing worldwide. Few alternative drugs are available that includes amphotericin B, pentamidine and miltefosine (oral). Already, decreases in efficacy, resistance and toxicity have been noted against these drugs. Dry antileishmanial pipeline further indicates the slow pace of drug discovery in this field where resistance as a major barrier. Full understanding of the genetic and molecular basis of the parasite is lagging. Since leishmaniasis is a neglected disease and occurs predominantly in the developing world largely, therefore, it is unaddressed. The pharma industry argues that development of the new drug is too costly and risky to invest in low return neglected diseases is very high. Research is also needed to identify new and effective drug targets. The lack of drug research and development for neglected diseases will require some new strategies. We have discussed the various cause of slow pace of antileishmanial drug discovery in this review to pay attention of researchers and also take the public and private initiative to make the process fast for new antileishmanial drug development.

For many years, virtually all pharmaceutical companies had an agrochemical division. This was partly to maximize the benefits of expensive chemical synthesis efforts by searching for many types of useful biological activities. Leads for pharmaceuticals and pesticides often overlap, in some cases leading to similar compounds used for human health and weed management purposes. This review will focus on herbicides and herbicide classes that have potential pharmaceutical properties, both as therapeutic agents that act through human molecular target sites and those that act on infectious agents. An example of the first case is compounds that target plant acetyl coenzyme A carboxylases, inhibiting fatty acid synthesis, and similar compounds used in humans as anti-inflammatory agents. Another such example is the triketone class of compounds that can act both as herbicides and as treatments for the genetic disease tyrosinemia, targeting the same enzyme in both cases. Examples of the second case are the relatively large number of herbicides that have activity against the malaria protozoan (Plasmodium spp.). It turns out that Plasmodium spp. and related disease organisms have an organelle that is apparently analogous to the plant plastid, the apicoplast. Herbicides such as dinitroanilines are active against several protozoan parasites by the same mechanism by which they kill plants, interaction with tubulin to halt cell division and other tubulin-dependent processes. These and other multiple activities of various herbicides and herbicide classes provide perspective on the broad biological activity of herbicides and related compounds.

Objectives: Companion diagnostic tests (CDx) are used to measure an individual's protein or gene expression (biomarkers) to inform choice of therapy. The increasing number of drugs requiring CDx poses challenges for regulatory and reimbursement policies. To better understand this issue, an environmental scan was conducted by the Canadian Agency for Drugs and Technologies in Health (CADTH).

Methods: The environmental scan was based on a focused literature search and feedback solicited from targeted stakeholders.

Results: The global market for CDx is expected to grow considerably until the end of this decade, with compound annual growth rate around 20 percent. Several factors may impact the adoption of CDx, including the potential cost-savings associated with reduced treatment failures and adverse reactions. Anticipating an expansion in drugs with CDx, some countries have updated their regulatory frameworks, including the United States where the FDA released new guidance in 2014. With respect to reimbursement, both the United Kingdom and Australia updated their evaluation frameworks to inform reimbursement decisions; however, several countries, including Canada, have not published policies for co-dependent technology.

Conclusion: The market size for CDx is expected to considerably expand in the future. The drive in uptake may be influenced by many factors including an increased knowledge of biomarkers and molecular drivers of disease and the potential cost-savings associated with fewer treatment failures and adverse reactions. Assessing whether such benefits materialize is important. Health technology assessment will play an important role in informing policies regarding the clinical use and funding of pharmaceuticals with CDx.

Powder diffraction data are presented for Ivabradine hydrochloride (pure and solvated forms), a drug marketed worldwide for symptomatic treatment of angina pectoris and inappropriate sinus tachycardia. [Ivrabradine: 3-[3-({[(7S)-3,4-dimethoxy bicyclo[4.2.0]octa-1,3,5-trien-7-yl]methyl}(methyl)amino)propyl]-7,8-dimethoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-2-one]. Many are the different (polymorphic or solvated) phases claimed in the scientific or forensic literature. We have here prepared monophasic samples of six different ivabradine hydrochloride species. Exposure to water vapours, at room temperature, of the anhydrous δ-d form generated pure powders of the tetrahydrate form (the β-form). Two different anhydrous forms (β-d and α) were prepared by gentle, or extensive, heating of the β and δ-d forms, respectively. Acetonitrile and acetone solvates (hereafter called δ1- and δ2-forms) were obtained by precipitation methods from concentrated solutions. Diffraction data were collected on laboratory equipment with Ni-filtered CuKα radiation; cell parameters and space groups were determined from ab initio indexing procedures using the SVD algorithm.
