Abstract:

Ant gardens (AGs) are a multi-partner specialized ant-plant interaction involving several ant and epiphyte species. Although studies on AGs have reported possible roles for some species in this system, there are unanswered questions regarding the process of epiphyte incorporation in the AGs and the role of less aggressive ant species in AG protection. In this study, we used AGs in the Brazilian Amazon forest formed by two parabiotic ant species to test a set of hypothesis regarding two main questions: 1) How is AG plant community composition affected by the surrounding environment? 2) Does Crematogaster levior play a role in the chemical detection of herbivory in the AGs? After identifying epiphytes occurring at AGs at the forest edge and in the interior, we found that ant gardens in each environment exhibited different compositions, and that plant species bearing oil or extrafloral nectar glands were more frequent in AGs located in the forest interior than in those at the forest edge. By performing experiments with volatile compounds emitted from injured epiphytes, we detected that only Camponotus femoratus was responsive, responding almost eight times faster in response to plant extracts than water treatments. Our results support the idea that environmental conditions affect ant preference for feeding resources provided by epiphytes and consequently shape the structure of the epiphyte community in AGs. On the other hand, the role of C. levior in AGs remains unknown, since it seems to play no direct or indirect role in AG protection.

Abstract:

Today the pineal gland is one of the most “titled” endocrine glands, but interest in it has not diminished, but continues to increase. A Melatonin Club has been organized and operates, and Jounal of Pineal Research, Advances in Pineal Research, and European Pineal Society News are published. The rapid development of chronobiology led to the elimination of the leading role of the pineal gland and its hormone melatonin in the implementation of circadian, seasonal and annual rhythms of the most diverse functional systems of the body [1]. Despite this, the amount of modern literature in Russian, devoted not to some particular issues, but to the pineal gland and its pathology as a whole, is very limited.

Abstract:

The cerebral epiphysis (pineal gland) secrets melatonin and number of other proteins and peptides. It was thus hypothesized that antioxidant properties of epiphyseal proteins and melatonin could potentially benefit from exogenous therapies. In view of the therapeutic potential of these proteins, the present experiment was conducted to investigate the effect of buffalo epiphyseal proteins (BEP, at 100 μg/kg BW, i.p.) and melatonin (MEL, at 10 mg/kg BW, i.p) on changes in hepatic and renal antioxidant enzymes of adult female Wistar rats. Buffalo epiphyseal proteins significantly (P<.05) increased hepatic lipid peroxidation (LPO), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx), reduced glutathione (GSH), and renal LPO, catalase (CAT), GR, GSH, GPx levels as compared to control animals. Similarly, MEL treatment significantly (P<.05) up-regulated hepatic SOD and GPx activity, whereas CAT, GR, GPx, and GSH levels in renal tissues were increased while SOD and LPO remained unaffected. Buffalo epiphyseal protein treatment produced greater effects on hepatic GPx and renal CAT and GSH levels than did MEL. These findings support the conclusion that buffalo epiphyseal proteins and melatonin activate a number of antioxidant mechanisms in hepatic and renal tissues.

Abstract:

Klotho mutant (kl/kl) mice exhibit growth retardation after weaning, and previous electron microscopic examination of GH-producing cells in pituitary glands revealed a reduction in GH granules. However, it has not been known whether growth retardation in klotho mutant mice is related to the loss of GH function. We therefore examined whether treatment with GH could rescue the retardation of growth. At the end of 3 weeks of treatment with human GH, the body weight of wild-type (WT) mice was increased. In contrast, body weight was not increased in klotho mutant mice even after the treatment with human GH. Another feature of klotho mutant mice is the presence of osteopetrosis in the epiphyses of long bones and vertebrae. Treatment with human GH increased trabecular bone volume in the epiphyseal region of WT tibiae. Interestingly, increase in trabecular bone volume by GH treatment was also observed in klotho mutant mice and, therefore, the phenotype of high bone volume in the klotho mice was further enhanced. These findings indicate that a GH receptor system in cancellous bones could operate in mutant mice. Thus, growth retardation in the klotho mutant mice is resistant against GH treatment even when these mice respond to GH treatment in terms of cancellous bone volume.

Abstract:

Pineal gland is one of the most important components of homeostasis - the supporting system of the body. It participates in the launch of stress responses, restriction of their development, prevention of adverse effects on the body. There was proved an impact of electromagnetic radiation on the epiphysis. However, morphological changes in the epiphysis under exposure to electromagnetic radiation of modern communication devices are studied not sufficiently. For the time present the population is daily exposed to electromagnetic radiation, including local irradiation on the brain. These date determined the task of this research - the study of the structure of rat pineal gland under the exposure to electromagnetic radiation from personal computers and mobile phones. These date determined the task of this research - the study of the structure of rat pineal gland under the exposure to electromagnetic radiation from personal computers and mobile phones. Performed transmission electron microscopy revealed signs of degeneration of dark and light pinealocytes. These signs were manifested in the development of a complex of general and specific morphological changes. There was revealed the appearance of signs of aging and depletion transmission electron microscopy both in light and dark pinealocytes. These signs were manifested in the accumulation of lipofuscin granules and electron-dense "brain sand", the disappearance of nucleoli, cytoplasm vacuolization and mitochondrial cristae enlightenment.

Abstract:

The study analyzed the prevalence of hypertension and impaired melatonin-forming function of the epiphysis in patients with stage 5 chronic kidney disease treated with hemodialysis. The relationship between epiphysis dysfunction and hypertension has been identified. 130 persons (50% of men) undergoing permanent hemodialysis treatment were examined. Controls were 20 healthy individuals. The determination of daytime and nighttime levels of melatonin in saliva and clinical and laboratory studies. As a result of the study it was found that for patients with stage 5 chronic kidney disease undergoing treatment, there is a frequent violation of melatonin-forming function of the pineal gland (84.6%) and hypertension (78%). In hemodialysis patients, blood pressure increases are age-dependent and are determined with salivary melatonin levels.

Abstract:

Melatonin is a hormone produced by the epiphyseal gland. Its physiologic functions have been extensively studied during the last years, its cyclic secretion seeming associated with multiple normal biological processes. Its correlation with autism has long been researched by some authors with the purpose to find a better therapeutically approach for a relative common disease of childhood. This paper reviews the accumulated scientific data in order to better understand the possible melatonin use in autistic symptoms treatment.

Abstract:

Ночная работа приводит к десинхронизации биоритмов, нарушению мелатонинобразующей функции и ускоренному старению эпифиза человека. Одним из перспективных геропротекторов, восстанавливающих синтез эпифизарного мелатонина, является пептид AEDG ( Ala-Glu-Asp-Gly ). Последний в 1,7 раза повышает экскрецию 6-сульфатоксимелатонина в моче людей среднего возраста, у которых этот показатель исходно снижен. Кроме того, у людей со сниженной мелатонинобразующей функцией эпифиза, пептид AEDG нормализует повышенную экспрессию циркадных генов Clock и Csnk 1 e в лейкоцитах и в 2 раза повышает сниженную экспрессию гена Cry 2 в лимфоцитах крови. В основе геропротекторного эффекта пептида AEDG лежит его способность восстанавливать мелатонинобразующую функцию эпифиза через регуляцию экспрессии часовых генов человека. Night work provides biorhythms desynchronization, disorder of melatonin-producing function and accelerated pineal gland aging. One of the promising geroprotectors restoring the pineal melatonin synthesis is the AEDG ( Ala-Glu-Asp-Gly ) peptide. AEDG peptide increases in 1,7 times the 6-sulfatoxymelatonin (6-SOMT) excretion in the urine of middle-aged people. Moreover, AEDG peptide normalized circadian Clock and Csnk1e genes hyper expression in leukocytes in 1,9-2,1 times and increases the Cry 2 gene hypo expression in peripheral blood lymphocytes in 2 times in people with reduced melatonin-producing epiphysis function. The geroprotective effect of the AEDG peptide is based on its ability to restore the epiphysis melatonin-producing function by means regulation of human circadian genes expression.

Abstract:

The chemistry of the floral oils of Phymatidium delicatulum and P. tillandsioides (Orchidaceae) is described. These small epiphytes produce the oils in a complex gland (the elaiophore) located on the median petal. The floral oils of P. tillandsioides were shown to be comprised mostly of acylglycerols, as in many other Oncidiinae orchids from southeastern Brazil. Surprisingly, the floral oil of P. delicatulum was composed, predominantly, of relatively simple linear hydrocarbons. Evidence that P. delicatulum is pollinated by females of the oil-gathering bee genus Tetrapedia (Apidae: Tetrapediini) is presented.

Abstract:

This chapter discusses pituitary disorders, focusing on prolactinoma, acromegaly, and pituitary apoplexy. A prolactinoma (prolactin-secreting pituitary tumour) is defined as a macroprolactinoma when it is >1 cm in diameter, and as a microprolactinoma when it is <1 cm in diameter. Acromegaly occurs as a result of excessive secretion of growth hormone (GH) and, consequently, of insulin-like growth factor 1 in adults. It is termed pituitary gigantism in the paediatric setting when excessive GH secretion occurs prior to epiphyseal plate fusion. Pituitary apoplexy is infarction of the pituitary gland, via haemorrhage or ischaemia, with resulting hypopituitarism. The etiologies, symptoms, diagnosis, investigation, prognosis, and treatment of these pituitary disorders are also discussed.

Abstract:

This chapter describes the pineal gland’s structure, related hormones, and physiology. The pineal gland (epiphysis cerebri) is a small (100–150 mg in humans), unpaired central structure. The mammalian pineal is a secretory organ, whereas in fish and amphibians it is directly photoreceptive (the ‘third eye’) and in reptiles and birds it has a mixed photoreceptor and secretory function. The main mammalian cell type is the pinealocyte, considered to have evolved from photoreceptor cells. This chapter discusses melatonin’s metabolism, and the pineal gland’s function in seasonal rhythms and circadian rhythms. It discusses pineal gland-related pathology, including tumours and cancer. The chapter also discusses the use of melatonin, in clinical practice, describing the hormone’s therapeutic benefits in circadian rhythm disorders.
