INTRODUCTION
Ca125 is a well-known marker of many malignant and nonmalignant diseases the majority of which are characterized by serosal involvement [1]. Mesothelial secretion of Ca125 rather than direct production by the neoplastic or inflammatory cells seems to underlie this phenomenon [2]. Thus, Ca125 qualifies as a marker of serosal, either peritoneal or pleural, involvement. Not surprisingly, rising levels of Ca125 have been

reported to characterize recurrent polyserositis in the context of familiar Mediterranean fever or systemic lupus erythematous [3]. In these cases it was observed an increase in Ca125 concentration in patients with active disease, but Ca125 has not been used as marker of exacerbations.
were heralded by increased Ca125 serum levels, making thus the periodical and on demand measurement of Ca125 a valuable means for a preclinical diagnosis of the recurrence.

We report a case of recurrent polyserositis in which exacerbations
CASE REPORT
In November 2008 a 69 year old lady came to our attention for recurrent polyserositis. Her clinical history dated back to May 2008, when she was hospitalized elsewhere for fever, abdominal tension and dyspnea. Erythrocyte sedimentation rate was 23 mm/h, ferritin 341 mg/dl (normal values [n.v.]: 11-307 mg/dl), LDH 542 mg/dl ( 0-250 mg/dl), GGT 113 mg/dlU/l (n.v. 12-48 U/l), total bilirubin 2.3 mg/dl (n.v. 0.3-1 mg/dl), indirect bilirubin 1.8 mg/dl (0-0.4 mg/dl), Ca125 57 mg/dlU/ml (n.v. 0-35 U/ml). Mucoproteins were 187 mg/24H (n.v. 0-6 mg/dl), D-dimer 2338 mg/dl (n.v<259 mg/dl). The HbsAg and HbsAb, HBe Ab, and HBcAb (IgG) were positive, as were the HAVAb IgG. Antitoxoplasm and anti-citomegalovirus IgG were 5.1 UI/ml (n.v.<12 UI/ml) and 246.7 UI/ml (n.v.<14 UI/ml), respectively, the Widal-Wright test was negative. Serologic tests for ANA, ANCA, rheumatoidfactor and ENA screening were all negative. The lymphocyte phenotype showed CD4 1341 cells/ mm3 (n.v. 700-1100/mmc), CD4/CD8 3.2 (n.v.: 1-1.5). A CT scan showed pulmonary consolidation, pleural and pericardium effusion, ascitic fluid and a hepatic nodular lesion in the VII segment having a diameter of 17 mm. A tentative diagnosis 3 of pneumonia and polyserositis was made and levoxacin 500 mg, furosemide 50 mg and prednisone 8 mg prescribed with remission of symptoms.
In September 2008, after discontinuation of prednisone, she had ascites and Ca125 rose to 122 mg/dl. A MNR of the abdomen showed nodular aspect of both annexes. She underwent bilateral annessiectomy and was treated with corticosteroid therapy. The histological examination showed reactive mesenchymal cells and few lymphocites in the ascitic uid, but normal ovaries and fallopian tubes. In November 2008 a biopsy

of the hepatic nodular lesion showed chronic hepatitis with mild portal and
intralobular focal activity interface; intralobular accumulation of nely
granular brown pigment in the cytoplasm of perivenous hepatocytes, groups of histiocytes containing ceroid pigment, outbreaks of hepatocyte degeneration with cytoplasmic ballooning. Immunohistochemistry showed positivity for HBsAg and negative for HBcAg Laboratory exams showed negative quantiferon and absence of antibodies against mitochondria.
In 2009, pleural and peritoneal effusions relapsed again, with observed values of Ca125 of 961 U/ml. A genetic study did not disclose MEFV mutation consistent with familial Mediterranean fever. The diagnosis of recurrent polyserositis was eventually conrmed and treatment with methylprednisolone 24 mg started and, then, tapered gradually over 3 months.
Two months after steroid discontinuation, a new relapse occurred and responded well to a new course of steroids. Afterwards, the patients was carefully monitored for relapsing pleural or peritoneal effusion by recording the weight, and a course of corticosteroid was administered at
rst signs of relapses, which usually were abdominal “fullness”, dyspnea,
edema and low grade fever. Later on, Ca125 was measured every three months, and prednisone was started when this marker at least doubled with regard to the last basal value, which occurred three times during one years, preventing thus the new onset of symptoms. This strategy has proved effective so far, although in the last couple of years the frequency of exacerbations has increased, with only about two weeks free of symptoms before a new treatment course is needed.
This case report conrms that Ca125 may be an indicator of the activity of serositis [4]. However, we add to the current knowledge by showing that exacerbations of recurrent polyserositis could be prevented and the related needs of steroids decreased by measuring Ca125 periodically and in the event of alarming symptoms such as feeling of rising abdominal tension and fatigue. The early intervention allowed to prevent or abort the exacerbation through a shorter course and lower cumulative dose of steroids. Furthermore, it prevented major symptoms such as abdominal pain, leg oedema and dyspnoea.
Interestingly, Ca125 increase also preceded the rise in inammatory markers, as if activation of mesothelial cells were the rst step of the

event, the risk exists that a spontaneous uctuation and not an impending
exacerbation accounts for increasing Ca125. Thus, a better knowledge of the dynamic of Ca125 would allow optimize the Ca125 based follow up strategy. Nevertheless, it is clear that in our patient monitoring Ca125 could improve the health status and reduce the use of steroids.

ABSTRACT
The cure for Alzheimer’s disease involves searching for candidate compounds that can act as inhibitors for Acetylcholinesterase (AChE) enzyme. Regional cerebral blood flow can be increased in patients with Alzheimer’s disease by Acetylcholinesterase inhibitors. In this regard, Tetraphenylporphinesulfonate (TPPS), 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron(III) Chloride (FeTPPS) and 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinatoIron(III) nitrosyl Chloride (FeNOTPPS) were investigated as candidate compounds for inhibition of Acteylcholinesterase of Drosophila melanogaster (DmAChE) by use of Molecular Docking. FeNOTPPS was found to form the most stable complex with DmAChE.

INTRODUCTION
Alzheimer’s disease is a progressive neurodegenerative disorder. Brain regions that are associated with higher mental functions, such as the neocortex and hippocampus, are those affected by the disease [1]. The “Cholinergic Hypothesis” for Alzheimer’s disease proposes that degeneration of cholinergic neurons in the basal forebrain and the associated loss of cholinergic neurotransmission in the cerebral cortex and other areas contribute significantly to the deterioration in cognitive function seen in patients with Alzheimer’s disease [2] (Figure 1).
Figure 1: Proposed neurochemical changes in Alzheimer’s disease.
Acetylcholinesterase enzyme (AChE) is bound to cellular membranes
of excitable tissues at cholinergic synaptic junctions. It catalyzes the hydrolysis of Acetylcholine neurotransmitter present in the brain [3]. The structure of AChE is a 12-stranded mixed β-sheet surrounded by 14 α- helices. There is a catalytic triad present in the active-site gorge of the Acteylcholinesterase enzyme of Drosophila melanogaster (DmAChE) which consists of three amino acids, namely Ser238, His440 and Glu367 (Figure 2).
