(BQ) Part 1 book "Histopathology of the skin" presents the following contents: Histology of normal skin, techniques of skin biopsy, dermoepidermal junction, the cells of the skin and their identification, common terminologies used in dermatopathology, staining techniques in dermatopathology,... Invite you to consult.
Bacteria are non-chlorophyllated unicellular organisms that reproduce by fission and do not
present nuclear envelope. Gram´s stain is a staining technique used to classify bacteria based
on the different characteristic of their cell walls. Gram-positive or Gram-negative bacteria
are determined by the amount and location of peptidoglycan in the cell wall, exhibiting
different chemical compositions and structures, cell-wall permeabilities, physiologies,
metabolisms, and pathogenicities.
The endoplasmic reticulum (ER) and the Golgi apparatus both maintain their specific
morphology, composition, and function in spite of the exchange of proteins and lipids
between the two organelles through membrane trafficking. The morphology of the Golgi
apparatus is closely linked to the balance between anterograde (ER-to-Golgi) and retrograde
(Golgi-to-ER) transport. It has been reported that the inhibition of anterograde transport
leads to the redistribution of Golgi components to the cytoplasm or the ER (Storrie et al.,
1998; Ward et al., 2001; Miles et al., 2001).
When students move from the lecture hall to the microbiology
laboratory, they need help bridging the
gap between the theory and the practice of what they are
learning. The equipment is unfamiliar, the procedures
are unfamiliar, and many of the materials they are handling
are unfamiliar. Linking the information from their
classroom lectures to the laboratory procedures is necessary
for their ultimate success. Our goal for this
laboratory manual is to provide the bridge that helps
students integrate their classroom lectures with their
The diagnosis of pulmonary tuberculosis can be made by the detection of acid fast bacilli by direct microscopy, using carbol fuchsin stain and/or fluorochrome stain. Microscopy is a rapid method but lacks sufficient sensitivity and does not distinguish between different species of mycobacteria. The sensitivity of microscopy is often not more than 25-40% as compared to culture, but under ideal conditions, it is possible to achieve a rate of 60-70%.
(BQ) Part 2 book "Mohs surgery and histopathology: Beyond the fundamentals" presents the following contents: Introduction to laboratory techniques, microanatomy and neoplastic disease, pecial techniques and stains.
(BQ) Part 1 book "Pathology practical book" presentation of content: Microscopy of various types, histopathology techniques and routine staining, frozen section and special stains, urine examination II microscopy, semen analysis, intracellular accumulations, gangrene and pathologic calcification,... and other contents.
Tzanck Smear A Tzanck smear is a cytologic technique most often used in the diagnosis of herpesvirus infections [herpes simplex virus (HSV) or varicella zoster virus (VZV)] (see Figs. 173-1 and 173-3). An early vesicle, not a pustule or crusted lesion, is unroofed, and the base of the lesion is scraped gently with a scalpel blade. The material is placed on a glass slide, air-dried, and stained with Giemsa or Wright's stain. Multinucleated epithelial giant cells suggest the presence of HSV or VZV; culture or immunofluorescence testing must be performed to identify the specific virus.
In under-resourced hematology laboratories there is usually a missing step in the battery of
required investigations. Moreover, when some of the advanced diagnostic instruments can
be found then the problem of chronic inadequate and irregular supply of kits and services
The goals of experimental neuroscience research are fundamentally to gain mechanistic
understanding of the pathology of disease in order to identify appropriate
targets for potential pharmacological intervention and evaluation of putative therapies.
With the advances in gene manipulation and transgene technologies, we have
unprecedented ability to generate animal models of disease that more closely mimic
the clinical conditions.
Noninvasive techniques capable of investigating altered pathophysiologies are
now of paramount importance.
The Nongynecological Cytology Practice Guideline is a document for laboratories and is intended
for use primarily by cytologists – pathologists and cytotechnologists – who perform non-
gynecologic cytology analyses and report their findings to clinicians. It is not intended to represent
the standard of care for use in medico legal proceedings. Thus, this document focuses on
laboratory processes and related topics such as techniques of sample procurement, slide staining
and analysis, and cytology laboratory management.
