Resins are amorphous products of complex chemical nature. They are transparent or translucent solids, semi-solids or liquid substances containing large number of carbon atoms. They are hard, electrically non-conductive and combustible masses. They are usually formed in schizogenous or schizolysigenous cavities or ducts as end products of metabolism.
Most of the resins are heavier than water. They are insoluble in water, but soluble in alcohol, volatile oils, fixed oils, chloral hydrate and non-polar organic solvents like benzene and ether.
Synonyms: Radix Ginseng, Shin-seng.
Part Used:
The roots of the cultivated perennial herbs of Panax quinquefolium (American ginseng) and of Panax schin seng (Chinese ginseng) (Fam. Araliaceae).Collected from 5-6 years old plants, in autumn, carefully cleaned and dried.
Liquorice or licorice is the common name of Glycyrrhiza glabra, a flowering plant of the bean family Fabaceae, from the root of which a sweet, aromatic flavouring can be extracted. The liquorice plant is a herbaceous perennial legume native to the Western Asia and southern Europe.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Synonyms: Nutgalls, blue galls, Turkish galls, mazoo
phal, gallotannic acid.
Biological source: Nutgall consists of the
pathological outgrowth obtained from the young
twigs of the dyers oak, Quercus infectoria Olivier,
belonging to family Fagaceae. Outgrowth is caused
by the puncture of ovums of gall wasp insect Cynips
tinctoria or Adleria gallaetinctoriae Olivier Family
Cynipidae.
Family: Fagaceae (dyers Oak), Cynipidae (gall wasp)
Nutgall
4.
Habitat: Oak galls are obtained principally from
Asiatic Turkey. Dyers oak is found in Turkey, Syria,
Iran, Cyprus, and Greece.
Characteristics: shape is globular or subspherical. 1-
2.5 cm in diameter with short basal stalk. Colour is
grey or white and the projections are dark brown in
colour. It has astringent taste.
5.
Collection: Gall wasp lay eggs on the twigs of oak
tree, when larvae come out of eggs, these larvae get
entered into the soft epidermis near the twigs where
they secrete enzyme that stimulate abnormal
vegetable outgrowth that is gall along with the
larvae inside (around the larvae). These larvae stay
inside for about 5-6 months. During this period,
larvae eat the carbohydrate portion and hollow the
galls. When they mature, they get out of the gall and
during whole of this process, gall changes its color
from bluish to grey and than white.
6.
The quality of galls depends upon the color they posses, they
can be classified as;
Blue gall (high quality gall)
Grey gall (medium quality gall)
White gall (low quality gall)
Color becomes white only, when insect leave outgrowth, collection
should be done at the time when larvae are still inside.
Insect should be removed laterly in order to collect tannins, grind
the plant part and utilize it.
If insect is inside at the time of grinding than it may cause
excessive hair growth because gall wasps are used to increase hair
growth.

overhead light and cannot tolerate shady situations. It is a
frost and draught resistant tree. The fruits ripen from
November to March depending upon the locality, and fall
soon after ripening. The mature fruits are collected from
January to April by shaking the trees, and then drying by
spreading in thin layers preferably in shades. The dried
myrobalan fruits are graded under different trade names.
Gradation is done on the basis of fruits colour, solidness,
and freedom from insect attack.
