Actinomycetes and Nocardia, Bacteria but similar to fungi usually because of its morphological feature of forming a branching filament network, causing Actinomycosis, Actinomycetoma, Farmer's Lung, etc. Demonstrated under microscope by Gram's stain and ZN staining. Cultured on BHI and Thioglycolate broth. Characteristically produce Supher granules. Penicillin is the drug of choice in allergic to penicillin can be replaced by Erythromycin or Tetracycline. In worst cases surgical removal of affected tissue required.

Acinetobacter: Awakening of a sleeping demonShyam Mishra
Acinetobacter is an emerging pathogen associated with several infections, in particular hospital-acquired infections. It is notorious for its multidrug resistance property. It is a great nuisance for the clinicians, microbiologists and a subject of great research for the scientists.
As the channel name suggests, our channel will be a perfect lounge for the malayali medicos..we wil be covering videos which will be like lecture classes related to the subjects biochemistry and microbiology in which we are specialised.. It will be a better learning experience for the students especially for those who are not able to understand and follow the normal classes in college..we assure the students that you will get a basic idea regarding the topic and extra reading can be done from the reference textbooks..

Nocardiosis
It is a rare infectious disorder which affects the lungs or the entire body means it become systemic and causes disease in different parts of the body.
Such as lungs, CNS, GIT, skin, heart, kidneys, eyes, muscles and joints infections.
Bacterium from the genus Nocardia, especially Nocardia asteroides and Nocardia brasiliensis, is mainly responsible for the occurrence of this condition.
Individuals with a weakened immunity due to some health problem are more at risk of developing this bacterial infection.
It causes diseases in humans and as well as cats, dogs, birds, fishes and cattle.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
2. Actinomyces:
Genus of the actinobacteria
Prokaryotic organisms :
Classified as bacteria,
but are unique enough
to be discussed as an individual
group.

3. Actinomyces:
Genus of the actinobacteria
Genus of the actinobacteria class of bacteria.
Gram-positive
Facultatively anaerobic
Except A.Meyeri & A. Israelii
: obligate anaerobe
Grow best under anaerobic conditions.
4. PROPERTIES
Actinomyces : species may form endospores,
Individual bacteria : rod shaped,
Actinomyces colonies : form fungus-like
branched networks of hyphae.
The aspect of these colonies initially led to
the incorrect assumption that the organism
was a fungus and to the name actinomyces,
"ray fungus" :from greek actis, ray, beam
and mykes, fungus.
6. life cycle of sporulating actinomycetes
• Order Actinomycetales
• Any member of a heterogeneous group of gram-
positive
• Generally anaerobic bacteria noted for a
filamentous and branching growth pattern that
results, in most forms, in an extensive colony, or
mycelium.
• The mycelium in some species may break apart
to form rod- or coccoid-shaped forms.
7. Actinomycete
