Patient discussion about duplication

Q. what is the cause for double vision

A. Double vision, or diplopia, as it's called, may be due to many conditions, including disorders of the muscles of the eye (extra-ocular muscles) and the nerves controlling them, disorders of the eye ball (enlarged eyeball as in Graves' ), and sometimes disorders of vision.

Diplopia may manifest important conditions, so consulting a doctor (e.g. neurologist or ophthalmologist) may be wise.

Q. I have fibromyalgia and am having terrible vision problems...double, blurred, feel off blance.Is this common?

A. Blurry vision is not a usual symptom in fibromyalgia. If you are experiencing this on a permenant basis you should see a doctor- either a neurologist or an ophthalmologist to rule out other vision conditions that might be causing this.

(5) To allow relief for economic loss, loss disallowance does not apply to stock of a subsidiary to the extent the loss exceeds a share's allocable part of the sum of (1) the aggregate earnings and profits resulting in positive investment adjustments and distributions from current earnings and profits (determined without regard to extraordinary gain dispositions described below) for all consolidated return years, (2) earnings and profits from certain extraordinary gains after November 18, 1990, net of directly related expenses, for all consolidated return years, and (3) the amount of duplicated loss (Prop.
Computed tomography (CT) scan showed bilateral distal ureteral stones: 8 mm in the left and about 2 cm in the right ureter with bilateral duplicated collecting system; the ureter draining the upper pole of right kidney was dilated (Fig.
It generally eliminates gains and losses on preferred stock and equalizes gains and losses on common stock, but may not necessarily eliminate all duplicated losses.
Once again, the BRR neutralized the potential for a $30 duplicated loss created by the contribution of land to S and the reduction in the CS2 basis.
Under the rule, if after applying the basis-redetermination rule, a group member recognizes a loss on an S stock disposition and S remains in the group immediately thereafter, the selling member's stock loss is suspended to the extent of the duplicated loss.
Analyses of the genes indicate that a common ancestral DNA segment produced three genes: one that evolved to become the rhodopsin gene, a second that became the blue-pigment gene, and a third that duplicated in more recent evolution to become the green-and red-pigment genes.
In theory (and somewhat in practice), the LDR was designed to allow nonduplicated deductions for actual economic losses, while prohibiting duplicated losses and losses attributable solely to basis adjustments made pursuant to the consolidated return regulations.
In general, groups may recognize a loss on the sale of a subsidiary only to the extent such loss exceeds the sum of the extraordinary gain dispositions, positive investment adjustments and duplicated losses related to the departing subsidiary.
