This document provides information on gastrointestinal surgery procedures for dogs and cats. It discusses causes of foreign bodies in the gastrointestinal tract including swallowed needles, nuts, and bones. Symptoms of obstruction are described depending on the location in the stomach or intestines. Diagnosis involves case history, palpation, and x-rays. Surgical treatments mentioned include laparotomy, enterotomy, intestinal resection and anastomosis. Specific procedures for rumen impaction, traumatic reticulitis, and pericarditis in cattle are outlined. Three techniques for rumenotomy surgery - Weingarth's, Gotze's, and Andre's - are described in detail.

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.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
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.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

2. Foreign Bodies in The Gastro-
Intestinal Tract in Dogs and Cats
Causes
1-Swallowing of a needle with thread after playing with the
thread.
2.Swallowing of different types of rubber objects and
stoppers of penicillin vials.
3. Pieces of stones. 4. Pieces of bones.
4. Different types of nuts.
3. Foreign bodies in the stomach: have no
sure symptoms
• Loss of appetite.
• Changes in the temperament of the animal.
• Pain manifestation.
• Sometimes vomition of the stomach content
5. Diagnosis
• The case history is very important.
• Symptoms
• Palpation
• X-ray film
• X-ray film after a barium meal or capsule
• X-ray film after barium enema
10. RUMINAL IMPACTION
• Primary rumen impaction occurs in
buffaloes and cattle mostly with depraved
appetite.
• Most of these animals eat plastics, ropes
leather pieces and cloths
11. Clinical signs
•Tympany.
• Anorexia.
•Leather pieces can produce obstruction at the
reticulo-omasal orifice and most of them were
recovered from the reticulum
•Treatment
•Rumenotomy
12. Traumatic Reticuloperotinitis
•Traumatic reticulitis is a traumatic inflammation of
the reticulum without inflammation of its serous
membrane
•Reticulo-peritonitis It means penetration of the
wall of the reticulum by a hard object resulting in
localized reticulitis and peritonitis
13. Causes:
• Pieces of wire
• Nails, needles, pieces of iron, screws
• Nutritional deficiencies such as phosphorus
14. Pathogenesis
•ventral ruminal sac cannot do any harm
•omaso-abomasal orifice expelled with the
faeces through the abomasum and intestine.
•The reticulum, sharp foreign body penetrate
the mucosa, musculosa and then serosa.
•foreign body causes injury to the liver,
intestine and diaphragm (abdominal cavity),
•pericardium and lungs (thoracic cavity).
15. Symptoms
• Loss of appetite.
• Milk yield is significantly diminished.
• The head is somewhat stretched and the back is arched (thoracic
kyphosis and lumber lordosis).
• Stiffness of the forelegs and abduction of the elbows is noticed
• Turning the animal to one side
• The animal grunts and is usually alert
• Rumination is weak or absent
• Feces are firm and decreased in quantity
• Recurrent chronic tympany
• Temperature, heart rate, respiratory rate normal
16. Diagnosis

• From the symptoms.
• Pain tests
A- Raising the abdominal wall by means of a long
piece of wood
B- The withers test
C- Percussion of the region of the xyphoid
cartilage, sides of the chest and the abdominal wall
by means of a strong percussion harmer
D- The back test
E- Going up and down a hill
19. Traumatic Pericarditis (TP)
• Traumatic pericarditis results from
• penetration of a sharp foreign body into the
pericardial sac.
• First of all, the foreign body penetrates the reticulum
then the diaphragm and finely penetrates the
pericardium inducing pericarditis.
• The condition is observed in cattle more than buffaloes
and recorded mostly in pregnant animals at the latter
stages of pregnancy or soon after parturition
20. Clinical signs of TP
• A history of complete anorexia, loss of body weight and
reduction of milk-yield
• Sudden appearance of mandibular and brisket edema filling and
pulsation of the jugular vein
• In some cases, edema of the thoracic limbs and ventral
abdominal wall was clear.
• Arched back and winged elbows were evident in many cases.
• Auscultation revealed muffled heart sound and dyspnia,
increased pulse rate and rise of body temperature up to 40C.

23.
24. Necropsy findings of Tp
• Adhesions between the reticulum, diaphragm and
pericardium are observed.
•Hydrothorax is seen in some cases.
•A fibrous tissue cord connecting the reticulum and
pericardium is seen in many cases
•In all cases, purulent exudates, often mixed with fibrin, are
filling the pericardial sac
25. Treatment of traumatic reticulitis
(
(Rumenotomy
• Indication:
• Traumatic reticulitis or reticulo-peritonitis.
• Persistent impaction of the rumen.
• Intoxication with toxic plants or food.
• For diagnosis
26. • The operation is performed with the animal in the
standing position either in a stanchion or box stall.
• A kicking strep is applied above the hocks.
• Tranquilization of the animal is indicated, xylazine HCl
(Rumpon) in a dose rate of 0.05 mg/kg B.W. is used.
• Anaesthesia is by a para-vertebral block or linear infiltration
inverted “L” field block analgesia
• Food and water should be withheld from the patient 24 hours
prior to surgery. Although this is not essential in emergency
cases.
• The left flank area is prepared for aseptic surgery
Animal control:
29. Weingarth’s technique for rumenotomy
• Preparation of flank region
• Hand breadth from last rib and hand breadth from lumbar
vertebrae and the incision performed parallel to last rib
• The incision must be long enough to admit the surgeon’s hand
(18-20 cm). The scalpel passed till the peritoneum, in the
following layers:
• Skin.
• Subcutaneous tissue.
• External oblique m.
• Internal oblique m. (aponeurosis).
• Transverse abdominal muscle

34. Andre’s technique for rumenotomy
• Proceed as described in weingarth’s technique till the
rumen is reached,
• then grasped with the hand and a large fold is taken out
through the abdominal wall incision.
• Two strong ruminal forceps are applied to the upper and
lower edges of the fold of the rumen and well fixed by an
assistant, so that the ruminal fold must kept outside the
abdominal wound.
• A sterile towel is placed around the protruding portion of
the rumen to protect the abdominal cavity from
contamination.
• A vertical incision is then made in the wall of the rumen by
means of a scalpel and widened by a scissors.
• Each lip of the rumen wound is grasped by an artery
forceps
35. Gotze’s technique for rumenotomy
• the ruminal fold is sutured to the parietal peritoneum and
fascia so that it can not return back on being released.
• The edges of the ruminal incision are lifted out of the
wound with hooks or forceps
• and fixed laterally, either to the skin
• or to fixation ring then using
• a special manschette to prevent contamination
