Acanthocephalans are among the most important and injurious groups of parasites infesting the fishes of India. It has been estimated that out of 800 reported species of acanthocephalans, 229 species are from India (Alfred, 1998). Fishes seem to tolerate high intensity of worms without showing pronounced symptoms of infection, and its complications (Taraschewski, 2000). Due to lack of symptoms in early stage of acanthocephalan infection in fishes, no diagnostic tool is available except postmortem investigations and identification by a helminth taxonomist. In the present paper, an account of a new acanthocephalan parasite recovered from the intestine of a marine fish Scatophague argus (Cuv. and Val.) from Deegha, West Bengal, has been given.

Acathocephalan of genus Raosentis are intestinal parasites of fresh water fishes. Subfamily Pallisentinae of order Gyracanthocephala includes four genera namely Acanthosentis (Verma & Datta,1929), Acanthogyrus (Thaper, 1927), Pallisentis (Van Cleave,1928) and Raosentis (Datta, 1947). The genus Raosentis was established By Datta (1947) with Raosentis podderi as its type species from a fresh water fish Mystus cavasius from Culcutta. The genus Raosentis differs from all the above genus in having proboscis armed with anterior two circle of hooks longer than posterior two circle with hook less space between second and third circle of hooks.

The genus Pleorchis Railliet, 1896 is designated to rare digenetic distomes living as parasite in the intestine of marine fishes, having numerous testes arranged in four longitudinal rows in hindbody. A total of 14 species have been attributed to the genus, while another 4 species are no longer considered the member of Pleorchis. In this study a new form is described and we critically overviewed the genus. Collection of two ovigerous specimens was recovered live at Deegha, West Bengal, India (Indian Ocean) from the intestine of a marine fish, Psettodes erumei (Bloch & Schneider) out of 40 examined. The present form differs from all nominal species of the Pleorchis in having 48 testes, unequal anterior intestinal caeca, vitellaria extending from a little anterior of ovary up to hind end of body and an entire unlobed ovary. In view of unique morphoanatomical characters it seems that the present form deserves the status of a new species with a specific name Pleorchis srivastavai n. sp. All known species of genus seems to be rare digeneans as evident by their respective studies and these are important link of marine ecosystem.

Adverse Environment and Pest Management for Sustainable Plant ProductionRahulGupta2015
In the era of rapid industrialization, there is increasing global concerns pertaining to anthropogenic activities mediated massive enhancement in atmospheric greenhouse gases like carbon dioxide, etc., thereby triggering global warming phenomenon. The global warming mediated climate change has been found to impose long-lasting detrimental impact on the environment. In contrast, adverse environment poses new unsightly challenges to agriculture sector like changes in precipitation pattern, temperature variations, pest infestation patterns and so on. Plant health management essentially contributes to socio-cultural sustainability, economic and environment sustainability as well as food security. The development of next-generation Integrated Pest Management programmes equipped with Artificial Intelligence, Bioinformatics and Biotechnology based tools would be a milestone for the protection of water, soil/land, wild species, environmental safety, improved plant productivity and profitability. This chapter provides an overview on the scientific approaches/strategies towards the prevention of climate change mediated impacts on agricultural plant/crop health and productivity with some notable eco-friendly pest management solutions. Overall, the better global treaties of coordination, cooperation and collaboration would lead to improved management of adverse environment and pests and plant/crop production can sustain the life on earth.
Endocrine role of osteocalcin in homeostatic regulation of glucose metabolismRahulGupta2015
Osteocalcin, a well-known bone formation marker, is secreted from osteoblasts and exists in fully carboxylated, partially carboxylated, and completely uncarboxylated forms. The endocrine involvement of uncarboxylated osteocalcin in glucose homeostasis has recently been confirmed. It has been demonstrated that double recessive osteocalcin mutant mice are hyperglycemic, hypoinsulinemic, and have reduced β cell numbers and insulin resistance. In contrast, leptin (an adipocyte-derived hormone) indirectly regulates the secretion of insulin in part through inhibition of osteocalcin conversion to uncarboxylated form via β2 adrenergic receptor signaling in osteoblasts. Because uncarboxylated osteocalcin is a secretagogue of insulin, which in turn positively regulates the bone formation, osteocalcin lies at the centre of the complex mechanism of glucose homeostasis and bone remodeling network.

Impact of Bioengineered Copper Quantum Dots on Germination, Photosynthetic Pi...RahulGupta2015
Cycles of light/ dark play a vital role in physiology/growth of plants by triggering different metabolic responses. Plants not only sense the commencement of dark stress environment but also utilize it for coordinating growth phenomenon. Likewise, copper as a vital micronutrient is needed by plants for mitochondrial respiration, antioxidant activity and so on. Currently, copper nanoparticles are receiving huge consideration owing to their economical, easier availability and so on. The present study examined the impacts of bioengineered copper quantum dots (Cu-QDs) in the range of 100-900 ppm on the seed germination, photosynthetic pigment as well as antioxidant response of darks stress environment exposed chick-pea (Cicer arietinum L.). The supplementation of 500-700 ppm Cu-QDs for 72 h under dark stress was significantly found to boost the germination of chick-pea seeds over control (that lacking Cu-QDs treatment). The photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoid) of dark and 600-700 ppm Cu-QDs treated chick-pea seedlings were also enhanced substantially over control. However, under the dark stress environment with the supplementation of 600-700 ppm Cu-QDs, the chick-pea seedlings recorded minimum antioxidant responses of reduced glutathione, glutathione reductase and ascorbate peroxidase compared to control. These results indicate the role of Cu-QDs as scavenging agent for reactive oxygen species (ROS). Overall, this investigation could be exploited to boost chick-pea seeds efficiency towards germination/ crop production during low-light intensity/ dark stress environment.

Cissus quadrangularis L. (hadjod) and Trigonella foenum-graecum L. (fenugreek) plant parts are used for fracture healing and as an antidiabetic agent, respectively in traditional medicine. This study aimed to investigate the efficacy of C. quadrangularis stem bark extract (CQ) and T. foenum-graecum seed extract (TFG) therapy for the treatment of type I diabetes induced osteopenia. Alloxan (dissolved in 0.1 M citrate buffer (pH = 4.5); intraperitoneally injected @ 130 mg/kg body weight) induced type I diabetic rats were treated with individual and combined doses of ethanol extracts of CQ and TFG for consecutive 30 days @ 250 and 500 mg per kg body weight, orally. Insulin (0.5 IU/kg body weight) was chosen as standard. Body weight and fasting blood glucose were recorded. Two-dimensional (2D) and three-dimensional (3D) analysis of the femur and tibia were performed using micro-computed tomography (µCT) scan to measure histomorphometric parameters of trabecular and cortical regions and bone mineral density (BMD). Elevated level of fasting blood glucose was restored to the vehicle-treated group after treatment with CQ and TFG. Both the extracts significantly improved trabecular histomorphometric parameters, viz. BMD, percent bone volume, trabecular number, trabecular separation, connection density. Cortical mean total cross-sectional bone area, cross-sectional thickness, mean total cross-sectional tissue area were comparable to the vehicle-treated group. CQ and TFG combination therapy showed a marked improvement in bone microarchitecture and can be given together as a potential alternative medicine to insulin for prevention of type I diabetes induced osteopathy. Therefore, it can be considered in the management of diabetic osteopathy in humans.

INTRODUCTION
During examination of intestine of marine fish, Drepane punctata (Cuv. &
Val.) collected from Deegha, West Bengal, three specimens of an
acanthocephalan parasite belonging to the genus Longicollum Yamaguti (1939),
including two female and one male, were recovered from the intestine of the host.
On subsequent study, the worm appears to be new and is described here in as new
species.
MATERIAL & METHODS
After proper washing, the parasites were kept III refrigerator. This
facilitated the complete eversion of the proboscis. The parasites were flattened
under slight pressure of cover glass and fixed in A.F.A. fixative (50% alcohol,
formalin and acetic acid in ratio of 100:6:2.5). The worms were stained in
aqueous Aceto alum carmine, differentiated in acid water, dehydrated through
ascending series of alcohol, cleared in xylol and mounted in Canada balsam. The
diagrams were made with the aid of camera lucida. All measurements are in
millimeter.

rom long and 0.26 mID wide at 1.53 mm from anterior end of trunk. Cement
glands are 6, pyriform, massed together far behind posterior testis, 0.20-0.25 rom
long and 0.10-0.11 mm wide. Saeffiigen's pouch is pyriform, 0.46 rom long and
0.18 nun wide. Bursa is elongated, without diverticula, 0.71 mm long and 0.21
mmwide.
FEMALE
Body is 9.30-10.95 mm long and 0.94-1.25 mm wide. Proboscis is 0.80-
0.98 rom long and 0.94-1.25 rom wide. Hooks of anterior region are 0.43-0.50
rom long, of middle region 0.032-0.040 rom long, of posterior region 0.044-0.052
rom long. Neck is 1.70-2.16 nun long and 0.38-0.40 mm wide. Trunk is 6.16-8.45
rom long and 0.94-1.25 rom wide. Proboscis receptacle is 2.75-3.21 rom long and
30
4. 0.15-0.16 mm wide. Lemnisci are 0.34-0.35 mm long. Uterine bell is short and
wide. Uterus is thick walled and with vaginal sphincter. Eggs were not observed.

DISCUSSION
The present form is referred to the genus Longicollum Yamaguti, 1935 of which
the following species viz., L. pagrosomi Yamaguti, 1935; L. alemniscus Harada,
1935 (syn. Spirorhynchus); L. minor Fukui and Morisita, 1936; L. chabanaudi
Dollfus and Go Ivan, 1963; L. indicum Gupta and Gupta, 1970; L. psettodesai
Gupta and Gupta, 1979; L. cadenati and L. quiloni Gupta and Naqvi, 1982 and L.
engraulisi Gupta and Fatma, 1983 are known so far. The present form chiefly
differs from all the above species except L. psettodesai, L. quiloni and L.
engraulisi in having equal lemnisci and 14 longitudinal rows of proboscis hooks.
It also differs from L. psettodesai, L. quiloni and L. engraulisi in the extension of
lemnisci a little anterior to proboscis receptacle and number of hooks per row in
proboscis. The new form further differs from L. quiloni and L. engraulisi in
ring testes pre-equatorial instead of post-equatorial. It is, therefore, regarded a
ies and named Longicollum dattai n. sp. in honour of Dr. M.M. Datta,
Zologi al ur 'e of India, Kolkata, for his outstanding contribution in taxonomy
of Acanthocephalan parasites,
