Catamenial and endometriosis-related pneumothorax are considered relatively rare entities. Their clinical characteristics outcome incompletely known.To evaluate the frequencies, characteristics, outcomes of catamenial pneumothoraces occurring in women with no underlying lung disease referred for surgical treatment.Clinical files all reproductive age to our center during a 6-year period treatment spontaneous were retrospectively reviewed. (CP) was defined as recurrent between day before...
This exploratory prospective study evaluated women's responses to questions that asked them describe how their body image and sexual functioning had changed since breast cancer diagnosis treatment.A questionnaire concerning scale various problems experienced after treatment was anonymously completed by 120 women in the outpatient clinic of our hospital's Division medical Oncology. To be eligible, subjects sexually active histology proven cancer. They also have received for cancer.100%...

Breast cancer is a critical public health issue and leading cause of cancer-related deaths among women worldwide. Its early diagnosis detection can effectively help in increasing the chances survival rate. For this reason, classification breast using Deep learning algorithms have attracted lot attention. Therefore, our study aimed to design computational approach based on deep convolutional neural networks for an efficient histopathological images by own created dataset. We collected overall...
Let K be a number field, n its degree, and d the absolute value of discriminant. We prove that, if is sufficiently large, then Dedekind zeta function ζ (s) has no zeros in region: [Formula: see text], where log M = 12.55 + 9.69n |ℑ𝔪 s| 3.03 58.63. Moreover, it at most one zero region:[Formula: text]. This exists simple real. argument also improves result Stark by factor 2: region
Patients with visceral crisis from luminal metastatic breast cancer (mBC) are often treated palliative chemotherapy. No studies have analyzed the aggressiveness of care in mBC patients. The objective this study was to assess practices setting a university medical oncology department.This retrospective included all patients who were managed for between January 2013 and April 2016. analysis focused on characteristics patients, modalities treatment delays death.Thirty-five pre-treated two...
The Riemann Zeta function $ζ(s)$ never vanishes in the region : $$ \Re s \ge 1- \frac1{5.70176 \log |\Im s|} \quad (|\Im s| 2).
We report here a 44-year-old Moroccan man with resectable gastric adenocarcinoma overexpression of human epidermal growth factor receptor 2 (HER2) by immunohistochemistry who was treated trastuzumab in combination chemotherapy perioperative setting. He received 3 cycles neoadjuvant consisting trastuzumab, oxaliplatin, and capecitabine. Afterwards, he total gastrectomy extended D2 lymphadenectomy without spleno-pancreatectomy. A pathologic complete response obtained oxaliplatin more...
In the ovary, metastatic malignant melanoma may be confused with primary and presents a diagnosis challenge. Most cases are associated disseminated diseases poor prognosis. We present this case report of ovarian simulating cancer. A 45-year-old premenopausal woman was incidentally found to have an abdominal mass, 3 years after removal cutaneous lesion. Ultrasound CT scan revealed left two solid masses, which were tumor at laparotomy. Left oophorectomy performed. Histopathology...
We prove an explicit bound for $N(\sigma ,T)$, the number of zeros Riemann zeta function satisfying $\mathfrak {Re}\,s\ge \sigma $ and $0 \le \mathfrak {Im}\, s T$. This result provides a significant improvement to Rosser's $N(T)$ whe
In this article we provide new explicit Chebyshev bounds for the prime counting function $\psi (x)$. The proof relies on two arguments: smoothing which allows one to generalize previous approaches, and a zero density estimate zeros of Riemann zeta function.
Invasive carcinoma of no special type (NST) or ductal is the largest group invasive breast cancers. lobular (ILC) second most common histological type; it comprises 5%–15% all Historically, neoplasia and may produce intracellular mucin that pushes nucleus to one side, creating characteristic signet ring cell morphology. The extracellular secretion essentially described in mucinous carcinoma. Mucinous differentiation can be seen small areas NST carcinoma, but recently a few cases with are...
Abstract Juvenile ossifying fibroma (JOF) and its variants, including juvenile psammomatoid (JPOF), represent rare yet clinically significant benign fibro-osseous lesions that primarily occur in children young adolescents. They can be found diverse anatomical sites such as the jaw, nasal cavity, paranasal sinuses, orbit. JOF exhibits an aggressive nature, necessitating early radiological detection surgical intervention. Similarly, JPOF, with a locally malignant potential, requires removal,...
This is a list of problems that were collected from participants at the Comparative Prime Number Theory Symposium held UBC June 17 to 21, 2024.

In this article, we prove a new bound for the least prime ideal in Chebotarev density theorem, which improves main theorem of Zaman [Funct. Approx. Comment. Math. 57 (2017), no. 1, 115â142] by factor $5/2$. Our improvement comes from version Turánâs power sum method. The key idea is to use Harnackâs inequality harmonic functions derive superior lower generalised Fejér kernel.
Management of localized primary gastric B lymphoma (PGL) remains controversial. The aim this study is to compare two treatments: chemotherapy alone and surgery plus chemotherapy. Records all patients with a diagnosis which were treated in the National Institute Oncology, between 1999 2006, reviewed fulfilling following criteria included study: histologically proven large-cell stomach; complete clinical information stage I/II disease according Musshoff staging; who received followed by (group...
Let be the Dirichlet -function associated to a non-principal primitive character modulo with . We prove new explicit zero-free region for : does not vanish in This improves result of McCurley where was shown an admissible value
We prove that if $x$ is large enough, namely $x\ge x_0$, then there exists a prime between $x(1- Δ^{-1})$ and $x$, where $Δ$ an effective constant computed in terms of $x_0$. This improves some previous results Ramaré Saouter used to verify the Ternary Goldbach Conjecture for integers up $7.86\cdot 10^{27}$.
