Kinesin-1
The most of the transportations in cells are realized through a kind of proteins, the molecular motor. Molecular motor can be classed into three families, myosin, kinesin and dynein. Kinesin-1 (also called conventional kinesin) is the founding member of the kinesin family and mainly exists in the nerve axons to transport membranous organelles along the microtubule lattice. By using the energy stored in the ATP molecule, kinesin-1 can “walk” along the microtubule lattice in a hand-over-hand manner. In the walking process of the kinesin-1, the conformational changes of the compact motor domain transmit and amplify the small changes of the nucleotide-binding site to the force-generation element to produce the processive movement. The chemical cycle and mechanical cycle of kinesin-1 are highly coupled to ensure the processivity of the kinesin-1 and to avoid the futile ATP hydrolysis.

Neutrophils in Obesity
Obesity is characterized by an increase in body weight associated with an exaggerated enlargement of the adipose tissue. Accumulation of fat in adipose tissue causes stress and malfunction of adipocytes, which then initiate inflammation. Next, adipose tissue is infiltrated by cells of the innate immune system. It has become evident that neutrophils, the most abundant leukocytes in blood, are the first immune cells infiltrating the adipose tissue. Neutrophils then get activated and release inflammatory factors that recruit macrophages and other immune cells. These immune cells, in turn, perpetuate the inflammation state by producing cytokines and chemokines that can reach other parts of the body, creating a systemic inflammatory condition.

Bt Brinjal
The Bt brinjal is a suite of transgenic brinjals (also known as an eggplant or aubergine) created by inserting a crystal protein gene (Cry1Ac) from the soil bacterium Bacillus thuringiensis into the genome of various brinjal cultivars. The insertion of the gene, along with other genetic elements such as promoters, terminators and an antibiotic resistance marker gene into the brinjal plant is accomplished using Agrobacterium-mediated genetic transformation. The Bt brinjal has been developed to give resistance against lepidopteron insects, in particular the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis)(FSB). Mahyco, an Indian seed company based in Jalna, Maharashtra, has developed the Bt brinjal. The genetically modified brinjal event is termed Event EE 1, and Mahyco have also applied for approval of two brinjal hybrids. The Event EE 1 was introgressed by plant breeding into various local varieties by University of Agricultural Sciences, Dharwad and Tamil Nadu Agricultural University, Coimbatore. Some of the cultivars of brinjal include: Malpur local, Manjari gota, Kudachi local, Udupi local, 112 GO, and Pabkavi local. It was approved for commercialization in India in 2009, but - after an apparent public outcry and rounds of debates in which representatives from Mahyco, the scientific community, and NGO's spoke on the topic - the then Indian Environment Minister, Jairam Ramesh, facilitated a moratorium on its release until further, unspecified, tests were conducted. Bt brinjal was approved for commercial release in Bangladesh in 2013.

Date Palm Fruits (Phoenix dactylifera L.)
The date palm (Phoenix dactylifera L.) is traditionally cultivated in arid regions of the world, including the Arabian Peninsula. It is one of the oldest fruit trees, a key component of the food system, and is recognized as a symbol of prosperity in the Arab world.

Effects of Colony Cages on Chickens
There is growing interest in keeping meat chickens in modern colony cages (CCs) rather than conventional litter-floor barns. Researchers aim to determine the animal welfare impacts of CCs using slatted flooring, in comparison to litter-based non-cage systems. Significant welfare concerns exist about CCs, centring around behavioural deprivation. Given that over 70 billion chickens are farmed then slaughtered each year globally, widespread implementation of CCs would create a major animal welfare concern.

Botrytis Cnerea and Powdery Mildew
Synthetic controls of crop pathogens are increasingly associated with harm to the environment and human health, and pathogen resistance. Pesticide residues in crops can also act as non-tariff trade barriers. There is therefore a strong imperative to develop biologically based and natural product (NP) biofungicides as more sustainable alternatives for crop pathogen control. We demonstrate the field efficacy, over multiple seasons, of NP biofungicides, NP1 (based on anhydrous milk fat) and NP2 (based on soybean oil), on two major diseases of winegrapes—Botrytis bunch rot (Botrytis) and powdery mildew (PM). The NPs were integrated into a season-long integrated disease management programme that has produced chemical-residue-free wines. Efficacies for Botrytis control on three different varieties were: 63–97% on Chardonnay, 0–96% for Sauvignon Blanc and 46–58% on Riesling; with 65–98% PM control on Chardonnay and Riesling. NP2 exhibited the significant control of Botrytis latent infections, making it a viable alternative to mid-season synthetic fungicides. Disease control was significantly better than the untreated control and usually as efficacious as the synthetic fungicide treatment(s). Yields and wine quality in NP-treated crops were normally equivalent to those in the synthetic fungicide treatments. The results indicate that NP-mediated disease control of Botrytis and powdery mildew can be obtained in the vineyard, without synthetic fungicide input.

Acinonychini
The feline tribe Acinonychini contains three genera, each with one extant species: the cougar in Puma, the jaguarundi in Herpailurus, and the cheetah in Acinonyx. In addition, a handful of extinct fossil species have been found in Eurasia and the Americas. The evolutionary relationships of these cats still needs to be worked out, with the main focus being the placement of the extinct species in relation to the extant species, and where cheetahs evolved. While cheetahs and cougars are sometimes considered big cats, as felines, they are more closely related to domestic cats than they are to pantherines such as lions and leopards.
