From Lab To Pharmacy Shelves: The Story Of A Plant Derived Anticancer Drug, "Paclitaxel", Maira Junjua, Sana Jafar, Fazeelat Karamat, Faheem Ahmed
Journal of Bioresource Management
Paclitaxel (Taxol®) is a highly praised anticancer drug, known for its efficiency in treating different cancers. It belongs to a class of compounds called taxanes that are derived from the plants of the genus Taxus. This drug is now FDA approved, but there was a time when the name Taxol was less known to the scientific world. Taxol, being a unique molecule in its structure, properties and mechanism of action, has undergone more than 30 years of trials, and faced a lot of hurdles to leave the bench of a laboratory and reach the shelves of a pharmacy. This review …

Status And Future Management Of Grey Goral (Naemorhedus Goral Bedfordi) In Pakistan, Fakhar -I- Abbas, Afsar Mian, Tanveer Akhtar, Thomas P. Rooney
Journal of Bioresource Management
Himalayan grey goral (HGG: Naemorhedus goral bedfordi) is endemic to Himalyas and regarded as Endangered/ Threatened. Study was designed to collect information on population biology, habitat, food and behaviour of population of HGG distributed in Pakistan, trying to understand its present status and conservational potentials. Our data suggest that the population, habitat and the species has sufficient potentials for its survival in the area, if protection from human predation is afforded to the species. HGG population is isolated into 7-8 subpopulations and is facing male-biased mortality, therefore is likely to face bottleneck effects and subsequent population crash ascribed to …

Dna Protective Activity Of Peels Of Some Vegetables Wastes, Aisha Ishaq, Kainaat William
Journal of Bioresource Management
The present study was conducted by using kitchen wastes like peels of different vegetables e.g. cucumber, potato, carrot, chickpea, cauliflower and pea, to evaluate the phytochemical constituents, DNA protection ability and free radicals scavenging activity. Phytochemicals tests showed the presence of carbohydrates, amino acids, glycosides, alkaloids, tannins and steroids in all samples while phlobatannins, anthraquonines and saponins were absent. The DNA protection of samples was checked by DNA protection assay using plasmid pBR322. Cauliflower and cucumber showed best protection at each dilution. DPPH free radicals scavenging assay was used to evaluate the antioxidant activity of peel extract of vegetables. Carrot …

Short Report: Description And Distribution Of Wagtails "Family Motacillidae" With Reference To Pakistan, Nadia Yousuf, Kainaat William, Madeeha Manzoor, Balqees Khanum
Journal of Bioresource Management
In the current study, Wagtails of the Family Motacillidae were studied in Pakistan. Thirteen species and sub-species were found in different regions. Their characteristics were observed, photographs were taken, previous distributions of these species were analyzed, and a new distribution of each species was reported in this study. During study, the scavenging role of these birds was identified, and it was hoped that wagtails may play an important role in the absence of the vultures after recent downfalls in major scavengers. However, these important effects were not observed in the wagtails, and probably will not occur until their populations increase …

In Vitro Culturing And Harvesting Of Human Plucked Hair Follicles, Iram Rehman, Attika Rehman, Samina Jalali
Journal of Bioresource Management
Human hair follicles are miniature hair growing organs. A common human hair disorder is androgenetic alopecia (AGA), which becomes a medical problem only when the hair loss is subjectively seen as excessive, premature, and distressing on the scalp. The objectives of the present study were to culture the hair stem cells in vitro and to study the morphology of the cultured cells for the treatment of AGA. The present study proposes that plucked human hairs are a cheap source to treat male baldness and in vitro culturing of hair follicle cells is the potential method to apply the cultured cells …

Journal of Bioresource Management
Himalayan musk deer (Moschus chrysogaste leucogaster) is an IUCN Red List Endangered species that reaches its western range limit in Pakistan, although its distribution or population size is unknown. Here, we mapped its distribution, described habitat preferences, estimated population sizes, recruitment and mortality, and reported the market values of musk deer wildlife products. We used two approaches: analyzing local wisdom (traditional ecological knowledge) through the use of questionnaires, and conducting confirmatory field surveys of selected areas. Questionnaire respondents indicated musk deer sightings in 28 of 84 localities; mainly in Himalayan dry temperate forests with >20% forest cover. There …

Review: Contribution Of Biotic Agents Of Pakistan In World Agriculture, Mohammad Irshad
Journal of Bioresource Management
Biological control has attained immense significance. Biological control is not unknown. It has a past history of successes. Natural control consists of two major components: environmental factors (abiotic) and natural enemies (biotic). Integrated Pest Management or Crop Management is considered a valuable tool in food security. It has not only been used in Pakistan but also Pakistani biotic agents have been used elsewhere in the world giving substantial economic control. These have been mainly used in the USA. With World Trade Organization protocols in operation, biological control will be of much significance. Import and export of natural enemies will be …

Journal of Bioresource Management
Medicinal plants have been widely used to treat a variety of infectious and non-infectious diseases. According to an estimate, 25% of the commonly used medicines contain compounds isolated from plants. Several plants could offer a rich reserve for drug discovery of infectious diseases, particularly in an era when the latest separation techniques are available on one hand, and the human population is challenged by a number of emerging infectious diseases on the other hand. Among several other ailments, fungal infections are posing a great threat to the mankind, as a large number of people suffer from fungal infections worldwide due …

Illegal wildlife trade is a great threat to the conservation efforts made worldwide to save wildlife species and their parts. Use of molecular methods, including DNA barcoding, is gaining acceptance to detect cross-border movement of endangered species. Here we report the utility of DNA barcoding in the detection of smuggling of an endangered turtle species from Pakistan. The consignment labeled as “fish meat” was intercepted at a Pakistani port and was tested for its source using DNA Barcoding with fish-specific primers. Sequences from the samples from this consignment matched (99%) with those from Lissemys punctata (Indian flap-shelled turtle), a species …

Biochar was used to replace inorganic fertilizers. Biochar was synthesized by the process of pyrolysis using horse dung (5kg) and dry grass (25kg) to check its effect on the growth of some local vegetables i.e. okra, beans, coriander and mint. These plants were kept in three different environments i.e. outdoor, indoor and greenhouse conditions. In each condition three replications were made for each plant and biochar was applied on them. Control plants (without biochar) were also grown in each condition. Parameters studied were pH, water holding capacity, ammonia, nitrates, chlorophyll content, fertility analysis, temperature and humidity, number of leaves, plant …
